In each of the four title compounds, namely (Z)-5-benzyl­idene-2-thio­xothia­zolidin-4-one, C10H7NOS2, (I), which crystallizes with Z′ = 2 in space group P21/n, (Z)-5-(4-methyl­benzyl­idene)-2-thio­xothia­zolidin-4-one, C11H9NOS2, (II), (Z)-2-thioxo-5-[4-(trifluoro­methyl)­benzyl­idene]thiaz­olidin-4-one, C11H6F3NOS2, (III), and (Z)-5-(4-methoxy­benzyl­idene)-2-thio­xothia­zolidin-4-one, C11H9NO2S2, (IV), there is a very wide C—C—C angle (ca 130°) at the methine C atom linking the two rings. Pairs of N—H⋯O hydrogen bonds link the two independent mol­ecules in (I) into a cyclic dimeric unit, and these units are further linked into complex sheets by three independent C—H⋯π(arene) hydrogen bonds. The mol­ecules of (II) are linked by paired N—H⋯O hydrogen bonds into centrosymmetric R22(8) dimers; the mol­ecules of (III) and (IV) are linked into chains of rings, which are constructed from a combination of N—H⋯S and C—H⋯O hydrogen bonds in (III), and from a combination of N—H⋯O and C—H⋯S hydrogen bonds in (IV).

Comment

As part of a programme for the synthesis of new fused heterocyclic systems of potential biological application, we have been evaluating the use of (Z)-5-aryl­methyl­ene-2-thioxothia­zolidin-4-ones as inter­mediates for cyclo­condensation reactions, and we report here the structures of four such compounds, (I)–(IV)[link], which have themselves been prepared by condensation of rhodanine (2-thio­xothia­zolidin-4-one) with ar­ylaldehydes using microwave irradiation in a solvent-free system.

The structure of (IV)[link] has been reported previously (Okazaki et al., 1998[Okazaki, M., Uchino, N., Ishihara, M. & Fukunaga, H. (1998). Bull. Chem. Soc. Jpn, 71, 1713-1718.]) using diffraction data collected at ambient temperature; however, no discussion of the supramolecular structure was given and there are no atomic coordinates deposited in the Cambridge Structural Database (Allen, 2002[Allen, F. H. (2002). Acta Cryst. B58, 380-388.]; refcode GOVXIY). Compound (I)[link] crystallizes in space group P21/n with Z′ = 2, while compounds (II)–(IV)[link] all crystallize with Z′ = 1; a careful search for possible additional symmetry in (I)[link] revealed none.

[Scheme 1]

In each of (I)–(IV)[link] (Figs. 1[link]–4[link][link][link]), the mol­ecules are nearly planar, as shown by the values of the torsion angle (Table 1[link]) defining the rotation of the ar­yl ring relative to the rest of the rigid skeleton. In addition, the meth­oxy C atom in (IV)[link] is virtually coplanar with the adjacent ar­yl ring. In each compound, there is a fairly short intra­molecular C—H⋯S contact (Table 2[link]), whose dimensions appear at first sight to suggest an attractive hydrogen-bonding inter­action forming an S(6) ring (Bernstein et al., 1995[Bernstein, J., Davis, R. E., Shimoni, L. & Chang, N.-L. (1995). Angew. Chem. Int. Ed. Engl. 34, 1555-1573.]). However, the bond angles associated with the central C—C—C fragment are all strongly indicative of a repulsive C—H⋯S inter­action; thus, the angles at the methine C atom linking the two rings are all around 130°. Moreover, the two exocyclic angles at thia­zolidine atom C5 consistently differ by ca 10°, and the exocyclic angles at benzene atom C61 consistently differ by ca 6°, always in the sense that the larger angle is that contained within the S(6) motif. All of these bond angles are thus consistent with a highly repulsive C—H⋯S contact, and it is noteworthy that the repulsive contact is accommodated by distortion of the skeletal bond angles in preference to a rotation about the C6—C61 bond, which might at first sight appear to be the less energy-costly solution. In this respect, the behaviour of compounds (I)–(IV)[link] resembles that of a series of 5-(aryl­methyl­ene)-1,3-dimeth­ylpyrimidine-2,4,6(1H,3H,5H)-triones, whose essentially planar mol­ecular skeletons are characterized by very wide C—C—C angles (ca 137–139°) at the bridging methine C atom (Rezende et al., 2005[Rezende, M. C., Dominguez, M., Wardell, J. L., Skakle, J. M. S., Low, J. N. & Glidewell, C. (2005). Acta Cryst. C61, o306-o311.]).

In each of (I)–(IV)[link], the ring angle at atom S1 is little greater than 90°, while in (IV)[link], the exocyclic bond angles at the ring C atom ipso to the meth­oxy substituent show the usual deviations from 120°.

The supramolecular structure of (I)[link] is considerably more complex than those of (II)–(IV)[link], and it is the only one of the series (I)–(IV)[link] in which C—H⋯π(arene) hydrogen bonds occur. For these reasons, we describe first (II)[link], which has the simplest supramolecular structure, then (III)[link] and (IV)[link], and finally (I)[link].

The mol­ecules of (II)[link] are linked by paired N—H⋯O hydrogen bonds (Table 2[link]) into a centrosymmetric R22(8) dimer (Fig. 5[link]), but the only direction-specific inter­action between these dimers is a dipolar carbon­yl–carbon­yl inter­action involving the C4—O4 bonds in the mol­ecules at (x, y, z) and (1 − x, 1 − y, 1 − z). The O4⋯C4i distance is 3.042 (2) Å and the C4—O4⋯C4i angle is 81.52 (9)° [symmetry code: (i) 1 − x, 1 − y, 1 − z], so that this inter­action typifies the nearly rectangular antiparallel type II motif (Allen et al., 1998[Allen, F. H., Baalham, C. A., Lommerse, J. P. M. & Raithby, P. R. (1998). Acta Cryst. B54, 320-329.]). The effect of this inter­action is to link, albeit weakly, the hydrogen-bonded dimers into a [100] chain. On the other hand, aromatic π–π stacking inter­actions and inter­molecular C—H⋯O and C—H⋯π(arene) hydrogen bonds are all absent.

The notional replacement of the meth­yl group in (II)[link] by a trifluoro­meth­yl group in (III)[link] causes a marked change in the supramolecular aggregation. The mol­ecules of (III)[link] are again linked into centrosymmetric R22(8) dimers, but now by means of paired N—H⋯S hydrogen bonds, as opposed to the N—H⋯O hydrogen bonds in (II)[link]. In addition, ar­yl atom C63 in the mol­ecule at (x, y, z) acts as a hydrogen-bond donor to ketone atom O4 in the mol­ecule at (−1 + x, −1 + y, z), so generating by translation a C(8) chain running parallel to the [110] direction. The combination of the two hydrogen bonds then generates a chain of edge-fused rings along [110], in which R22(8) rings centred at (n, n − [{1\over 2}], [{1\over 2}]) (n = zero or integer) alternate with R44(26) rings centred at (n + [{1\over 2}], n, [1\over 2]) (n = zero or integer) (Fig. 6[link]). The trifluoro­meth­yl groups lie on the outer edges of this chain; there are no direction-specific inter­actions between adjacent chains.

The supramolecular structure of (IV)[link] also consists of a chain of rings, but now constructed from a combination of N—H⋯O and C—H⋯S hydrogen bonds as opposed to the combination of N—H⋯S and C—H⋯O hydrogen bonds in (III)[link]. Pairs of mol­ecules are linked by N—H⋯O hydrogen bonds into a centrosymmetric R22(8) dimer, just as in compound (II)[link], and these dimers are linked by one component of a planar three-centre C—H⋯(S)2 inter­action (Table 2[link]). The shorter component in this system is probably a repulsive contact as discussed above, but the longer component appears to be attractive. Ar­yl atoms C62 in the mol­ecules at (x, y, z) and (2 − x, 1 − y, 1 − z), which form the R22(8) dimer centred at (1, [1\over2], [{1\over 2}]), act as hydrogen-bond donors, respectively, to thione atoms S2 in the mol­ecules at (1 − x, −y, 1 − z) and (1 + x, 1 + y, z), which themselves form parts of the R22(8) dimers centred at (0, −[1\over2], [1\over2]) and (2, [3\over2], [1\over2]), respectively, so generating by inversion a complex chain of rings running parallel to the [110] direction and containing S(6), R22(8) and R24(8) rings (Fig. 7[link]).

In (I)[link], where the two independent mol­ecules are related by an approximate, but not exact, twofold rotation, the mol­ecules are again linked by a pair of N—H⋯O hydrogen bonds (Table 2[link]) into a dimeric aggregate (Fig. 1[link]). These units are then linked into sheets by three independent C—H⋯π(arene) hydrogen bonds, and the formation of this sheet is very readily analysed in terms of two one-dimensional substructures, one generated by inversion and the other generated by a 21 screw axis.

In the first substructure, ar­yl atoms C163 and C266 at (x, y, z) act as hydrogen-bond donors, respectively, to ar­yl rings C261–C266 at (1 − x, 1 − y, 1 − z) and C161–C166 at (1 − x, −y, 1 − z), so generating by inversion a chain along ([{1\over 2}], y, [1\over2]) containing three types of ring, two of which are centrosymmetric (Fig. 8[link]). In the second substructure, which involves only one of the two independent mol­ecules, ar­yl atom C166 at (x, y, z) acts as a hydrogen-bond donor to the C161–C166 ar­yl ring at ([{3\over 2}] − x, −[{1\over 2}] + y, [{3\over 2}] − z), so forming another [010] chain, this time generated by the 21 screw axis along ([{3\over 4}], y, [{3\over 4}]) (Fig. 9[link]). The mol­ecule at ([{3\over 2}] − x, −[{1\over 2}] + y, [{3\over 2}] − z) forms part of the inversion-generated chain lying along (1, y, 1), and hence the combination of these two types of [010] chain generates a sheet parallel to (10[\overline 1]).

Experimental

Equimolar quantities (1 mmol of each component) of 2-thio­xothia­zolidin-4-one and the appropriate benzaldehyde 4-XC6H4CHO [where X = H for (I)[link], CH3 for (II)[link], CF3 for (III)[link] and CH3O for (IV)[link]] were placed in open Pyrex-glass vessels in the absence of any solvent and irradiated in a domestic microwave oven for 3 min (at 600 W); the reactions were monitored by thin-layer chromatography. The reaction mixtures were extracted with ethanol; after removal of this solvent, the products were recrystallized from dimethyl­formamide to give crystals suitable for single-crystal X-ray diffraction analysis.

For compound (I)[link], the space group P21/n was uniquely assigned from the systematic absences. Likewise, the space group P21/c was uniquely assigned for both (II)[link] and (IV)[link].

H atoms bonded to N atoms were allowed to ride at the N—H distances (0.90–0.93 Å) deduced from the difference maps [with Uiso(H) = 1.2Ueq(N)]. In (III)[link], the displacement parameters for the F atoms indicated some libration of the CF3 group, but it was not found necessary to model this group with more than three F-atom sites.

Comment top

As part of a programme for the synthesis of new fused heterocyclic systems of potential biological application, we have been evaluating the use of (Z)-5-arylmethylene-2-thioxothiazolidin-4-ones as intermediates for cyclocondensation reactions, and we report here the structures of four such compounds, which have themselves been prepared by condensation of rhodanine (2-thioxothiazolidin-4-one) with aryl aldehydes using microwave irradiation in a solvent-free system.

We report here the molecular and supramolecular structures of four (Z)-5-arylmethylene-2-thioxo-4-thiazolidines, compounds (I)–(IV). The structure of compound (IV) has been reported previously (Okazaki et al., 1998) using diffraction data collected at ambient temperature; however, no discussion of the supramolecular structure was given and there are no atomic coordinates deposited in the Cambridge Structural Database (CSD; Allen, 2002; refcode GOVXIY). Compound (I) crystallizes in space group P21/n with Z' = 2, while compounds (II)–(IV) all crystallize with Z' = 1; a careful search for possible additional symmetry in (I) revealed none.

In each of (I)–(IV) (Figs 1–4), the molecules are nearly planar, as shown by the values of the torsion angle (Table 1) defining the rotation of the aryl ring relative to the rest of the rigid skeleton. In addition, the methoxy C atom in (IV) is also virtually coplanar with the adjacent aryl ring. In each compound, there is a fairly short intramolecular C—H···S contact (Table 2), whose dimensions appear at first sight to suggest an attractive hydrogen-bonding interaction forming an S(6) ring (Bernstein et al., 1995). However, the bond angles associated with the central C—C—C fragment are all strongly indicative of a repulsive C—H···S interaction; thus, the angles at the methine C atom linking the two rings are all around 130°. Secondly, the two exocyclic angles at thiazolidine atom C5 consistently differ by ca 10°, and the exocyclic angles at phenyl atom C61 consistently differ by ca 6°, always in the sense that the larger angle is that contained within the S(6) motif. All of these bond angles are thus consistent with a highly repulsive C—H···S contact, and it is noteworthy that the repulsive contact is accommodated by distortion of the skeletal bond angles in preference to a rotation about the C6—C61 bond, which might at first sight appear to be the less energy-costly solution. In this respect, the behaviour of compounds (I)–(IV) resembles that of a series of 5-(arylmethylene)-1,3-dimethyl-pyrimidine-2,4,6(1H,3H,5H)-triones, whose essentially planar molecular skeletons are characterized by very wide C—C—C angles (ca 137–139°) at the bridging methine C atom (Rezende et al., 2005).

In each of (I)–(IV), the ring angle at atom S1 is little greater than 90°, while in (IV), the exocyclic bond angles at the ring C atom ipso to the methoxy substituent show the usual deviations from 120°.

The supramolecular structure of (I) is considerably more complex than those of (II)–(IV), and it is the only one of the series (I)–(IV) in which C—H···π(arene) hydrogen bonds occur. For these reasons, we describe first (II), which has the simplest supramolecular structure, then (III) and (IV), and finally (I).

The molecules of (II) are linked by paired N—H···O hydrogen bonds (Table 2) into a centrosymmetric R22(8) dimer (Fig. 5), but the only direction-specific interaction between these dimers is a dipolar carbonyl–carbonyl interaction involving the C4—O4 bonds in the molecules at (x, y, z) and (1 − x, 1 − y, 1 − z). The O4···C4i distance is 3.042 (2) Å and the C4—O4···C4i angle is 81.52 (9)° [symmetry code: (i) 1 − x, 1 − y, 1 − z], so that this interaction typifies the nearly rectangular antiparallel type II motif (Allen et al., 1998). The effect of this interaction is to link, albeit weakly, the hydrogen-bonded dimers into a [100] chain. On the other hand, aromatic π–π stacking interactions, and intermolecular C—H···O and C—H···π(arene) hydrogen bonds, are all absent.

The notional replacement of the methyl group in (II) by a trifluoromethyl group in (III) causes a marked change in the supramolecular aggregation. The molecules of (III) are again linked into centrosymmetric R22(8) dimers, but now by means of paired N—H···S hydrogen bonds, as opposed to the N—H···O hydrogen bonds in (II). In addition, aryl atom C63 in the molecule at (x, y, z) acts as a hydrogen-bond donor to the ketonic atom O4 in the molecule at (−1 + x, −1 + y, z), so generating by translation a C(8) chain running parallel to the [110] direction. The combination of the two hydrogen bonds then generates a chain of edge-fused rings along [110], in which R22(8) rings centred at (n, n − 1/2, 1/2) (n = zero or integer) alternate with R44(26) rings centred at (n + 1/2, n,1/2) (n = zero or integer) (Fig. 6). The trifluoromethyl groups lie on the outer edges of this chain; there are no direction-specific interactions between adjacent chains.

The supramolecular structure of (IV) also consists of a chain of rings, but now constructed from a combination of N—H···O and C—H···S hydrogen bonds as opposed to the combination of N—H···S and C—H···O hydrogen bonds in (III). Pairs of molecules are linked by N—H···O hydrogen bonds into a centrosymmetric R22(8) dimer, just as in compound (II), and these dimers are linked by one component of a planar three-centre C—H···(S)2 interaction (Table 2). The shorter component in this system is probably a repulsive contact as discussed above, but the longer component appears to be attractive. Aryl atoms C62 in the molecules at (x, y, z) and (2 − x, 1 − y, 1 − z), which form the R22(8) dimer centred at (1,1/2, 1/2), act as hydrogen-bond donors, respectively, to thione atoms S2 in the molecules at (1 − x, −y, 1 − z) and (1 + x, 1 + y, z), which themselves form parts of the R22(8) dimers centred at (0, −0.5,1/2) and (2, 1.5,1/2), respectively, so generating by inversion a complex chain of rings running parallel to the [110] direction and containing S(6), R22(8) and R42(8) rings (Fig. 7).

In (I), where the two independent molecules are related by an approximate, but not exact, twofold rotation, the molecules are again linked by a pair of N—H···O hydrogen bonds (Table 2) into a dimeric aggregate (Fig. 1). These units are then linked into sheets by three independent C—H···π(arene) hydrogen bonds, and the formation of this sheet is very readily analysed in terms of two one-dimensional substructures, one generated by inversion and the other generated by a 21 screw axis.

In the first substructure, aryl atoms C163 and C266 at (x, y, z) act as hydrogen-bond donors, respectively, to the aryl rings C261–C266 at (1 − x, 1 − y, 1 − z) and C161–C166 at (1 − x, −y, 1 − z), so generating by inversion a chain along (1/2, y,1/2) containing three types of ring, two of them centrosymmetric (Fig. 8). In the second substructure, which involves only one of the two independent molecules, aryl atom C166 at (x, y, z) acts as a hydrogen-bond donor to the C161–C166 aryl ring at (3/2 − x, −1/2 + y, 3/2 − z), so forming another [010] chain this time generated by the 21 screw axis along (3/4, y, 3/4) (Fig. 9). The molecule at (3/2 − x, −1/2 + y, 3/2 − z) forms part of the inversion-generated chain lying along (1, y, 1), and hence the combination of these two types of [010] chain generates a sheet parallel to (10–1).

Equimolar quantities (1 mmol of each component) of 2-thioxothiazolidin-4-one and the appropriate benzaldehyde 4-XC6H4CHO [where X = H for (I), CH3 for (II), CF3 for (III) and CH3O for (IV)] were placed in open Pyrex-glass vessels in the absence of any solvent and irradiated in a domestic microwave oven for 3 min (at 600 W); the reactions were monitored by thin-layer chromatography. The reaction mixtures were extracted with ethanol; after removal of this solvent, the products were recrystallized from dimethylformamide to give crystals suitable for single-crystal X-ray diffraction. For (I) (orange crystals, m.p. 478 K, yield 58%): MS (70 eV) m/z (%), 221 (23, M+), 134 (100), 108 (40), 89 (8), 51 (4), 77 (2).

For compound (I), the space group P21/n was uniquely assigned from the systematic absences. Likewise, the space group P21/c was uniquely assigned for both (II) and (IV). Although the unit cells for (II) and (IV) appear to have very different dimensions and shapes, with the b parameter for (II) nearly double that for (IV), both cells have values of β close to 90°, so that not only are their reduced cells similar in dimensions but both are close to orthorhombic metrics. Crystals of (III) are triclinic; the space group P1 was selected, and confirmed by the successful structure analysis. All H atoms were located from difference maps and then treated as riding atoms. H atoms bonded to C atoms were assigned C—H distances of 0.95 Å (aromatic and methine) or 0.98 Å (methyl) [with Uiso(H) = 1.2Ueq(C), or 1.5Ueq(C) for the methyl groups]. H atoms bonded to N atoms were allowed to ride at the N—H distances (0.90–0.93 Å) deduced from the difference maps [Uiso(H) = 1.2Ueq(N)]. In (III), the displacement parameters for the F atoms indicated some libration of the CF3 group, but it was not found necessary to model this group with more than three F-atom sites.
