Substituted pyrazoles have been the target of extensive research in a diversity of areas, e.g. biology, chemistry, pharmacology and medicine. From the biological side, the interest promoted by this type of compound has led to an important class of bioactive molecules in the pharmaceutical industry that includes such blockbuster drugs as Celebrex (Penning et al., 1997) and Viagra (Terrett et al., 1996). Pyrazole heterocycles are also of pharmacological interest as anti-anxiety, antipyretic, analgesic, anti-inflamatory, antiparasitic and antimicrobial drugs (Elguero et al., 2002), and some related derivatives have been described as potent PDE4B inhibitors (Card et al., 2005).
From the chemical side, pyrazole derivatives have been used as ligands for obtaining transition metal complexes, since the heterocycle may coordinate to the metal directly via one or both vicinal N atoms (Rojas et al., 2004).
Considering the synthetic route, we have been able to obtain two 4-hydrazinylidene-substituted 1H-pyrazol-5-ones [see a and b in Scheme 1 (top) (Bustos et al., 2009), where a is in principle a more rigid structure than b]. The hydrazinylidene group in a may generate diazenyl/hydrazinylidene tautomers, in both of which the keto O atom acts as an acceptor. In these tautomeric forms, a and a' (Scheme 1, bottom), the hydrazinylidene group adopts either a hydrazinylidene (–HN—N═) or diazenyl (–N═N–) form. Only one internal double bond is present in the pyrazole ring in the first form (a), while two formal and conjugated double bonds are formed in the second form (a'). In this case, the a' molecule gains stability because the pyrazole ring becomes an aromatic system, so that the stability of both species, viz. a and a', is markedly dependent on the strength of the resonance-assisted hydrogen bond (RAHB).
The present report, the first of an intended series of related papers describing the structures obtained, grouped according to their a(a') or b character, presents two new pyrazole compounds (denoted class a in our nomenclature above), viz. 3-methyl-4-[(Z)-2-(4-methylphenyl)hydrazin-1-ylidene]-1-(3-nitrophenyl)-1H-pyrazol-5(4H)-one, (I), with two independent molecules in the asymetric unit, and 3-methyl-4-[(Z)-2-(4-methylphenyl)hydrazin-1-ylidene]-1-[4-(trifluoromethyl)phenyl]-1H-pyrazol-5(4H)-one, (II) (Scheme 2).
Chemicals Reagents (ethyl acetoacetate, sodium nitrite, sodium acetate, sodium hydroxide, 4-methylaniline, 4-nitrophenyhydrazine, 4-(trifluorophenyl)hydrazine and glacial acetic acid) and solvents (ethanol, tetrahydrofuran, chloroform and chloroform-d) were procured from common commercial sources (Merck Chemical and Sigma–Aldrich) and used without further purification.
Preparation of the precursor Ethyl (Z)-3-oxo-2-(2-p-tolylhydrazinylidene)butanoate was prepared according to the method recommended in the literature (Yao, 1964; Bertolasi et al., 1999; Bustos et al., 2009) and was recrystallized from ethanol.
Preparation of (I) and (II) These compounds were prepared by mixing pure ethyl (Z)-3-oxo-2-(2-p-tolylhydrazinylidene)butanoate (2.48 g, 10 mmol), arylhydrazine (10 mmol) {(3-nitrophenyl)hydrazine (1.85 g, 97%) for (I) and [4-(trifluoromethyl)phenyl]hydrazine (1.68 g, 96%) for (II)}, glacial acetic acid (5 ml) and ethanol (30 ml). The mixture was stirred and heated under reflux near the boiling point, and a yellow–orange solid precipitate was obtained after 36 h. The reaction mixture was cooled at 263 K for 2 h and the solid which formed was filtered off by suction at room temperature, washed with an abundant quantity of water (500 ml) and dried in a vacuum oven at 313 K for 12 h. Single crystals suitable for diffraction studies were obtained by recrystallization of each compound from an ethanol–tetrahydrofuran (1:1 v/v) mixture.
Analysis of (I) and (II) For (I): yield 75.3% crude. Elemental analysis, calculated (%) for C17H15N5O3: C 60.53, H 4.48, N 20.76; found: C 60.72, H 4.63, N 20.77. For (II): yield 61.4% crude. Elemental analysis, calculated (%) for C18H15F3N4O: C 60.00, H 4.20, N 15.55; found : C 60.38, H 4.42, N 16.02.
Crystal data, data collection and structure refinement details are summarized in Table 1. All H atoms were originally found in difference maps, but they were treated differently in the refinement. N-bound H atoms were refined with restrained N—H distances [0.85 (1) Å] and free Uiso values. C-bound H atoms were repositioned in their expected positions and allowed to ride (methyl C—H = 0.96 Å and aromatic C—H = 0.93 Å) and the methyl? groups were allowed to rotate around their C—C bond. Riding H atoms were assigned a Uiso(H) value of xUeq(C), where x is 1.2 for aromatic and 1.5 for methyl H atoms.
In both (I) and (II) (Scheme 2), the nucleus is a type a pyrazole (see Scheme 1, bottom).
In (I), the outer substituents in the benzene rings are a 4-methyl group on one side and a 3-nitro group on the other. The compound crystallizes in the monoclinic space group P21/c with two molecules in the asymmetric unit (Z' = 2), viz. molecule (IA) (Fig. 1a) and molecule (IB) (Fig. 1b). The two units have only slight differences, as disclosed by the small mean unweighted deviation in their least-squares superposition, 0.18 (2) Å. PLATON (Spek, 2009) did not detect any obvious pseudosymmetry in the structure.
The overall molecular structure of (II) differs from that of (I) only in the presence of a 4-trifluoromethyl substituent on benzene ring 2 (see Figs. 1 and 2 for ring codes), but it has a very different crystal structure.
Both structures are very similar with respect to bond distances and angles, which do not deviate from the expected values and therefore will not be discussed in depth. However, we would like to stress for future reference the single–double bond sequence in the pyrazole rings (Table 2), clearly consistent with type a rather than type b nuclei, which will be the subject of a future contribution.
Molecules (I) and (II) are basically flat, but with slight individual deviations from coplanarity of lateral rings 2 and 3 with respect to the central pyrazole (ring 1). Thus, in molecule (IA), the dihedral angles between the planes of rings 1A/2A and 1A/3A are 5.25 (11) and 2.17 (11)°, respectively, while in the molecule (IB) they are a little larger, viz. 6.26 (11) and 10.14 (11)°. A similar situation is found with the out-of-plane rotation of the nitro group with respect to ring 2, which is 1.92 (11)° in molecule (IA) but 14.08 (12)° in molecule (IB). The corresponding angles for (II) [1/2 = 8.47 (17)° and 1/3 = 11.62 (18)°] show it to be slightly more out-of-plane.
Even if noticeable, these angles can be considered small if the (in principle) free rotation of the lateral rings involved is considered. Thus, it is tempting to ascribe this coplanarity to the presence of keto atom O1 at C7, which tends to make two intramolecular hydrogen bonds, rendering the coplanar arrangement more favourable and thus facilitating the hindering of any eventual rotation of the benzene ring around the N1—C1 bond.
However, a search of the Cambridge Structural Database (CSD, Version 5.34; Allen, 2002) suggests that this limitation can be easily overcome; there are many reported structures which have the same keto environment, but where the benzene and pyrazole rings are far from being coplanar [e.g. 27.60 (2)° (CSD refcode JEBMEI; Connor et al., 1990) and 23.44 (3)° (CSD refcode YICBIV; Skoweranda et al., 1994)]. This suggests that the role of the weak C—H···O hydrogen bond in providing for coplanarity will be relevant only in the absence of other stronger contacts, as is the case in the molecules of (I) and (II).
Perhaps the most interesting aspect in the comparison of these two structures lies in the effect which the interplay of the weak intermolecular interactions present (see hydrogen-bonding details in Table 3 and π–π interactions in Table 4) has on the supramolecular disposition.
In both structures, there are intramolecular hydrogen bonds for which the keto O atom is an acceptor [O1A and O1B in (I) (Fig. 1), and O1 in (II) (Fig. 2)] and these contribute to the general planarity of the molecules. The hydrazinylidene N—H group is involved in these contacts, a fact which probably inhibits further N—H intermolecular involvement.
The rest of the hydrogen-bonding interactions are of the C—H···O type, and give rise to very different substructures.
In the case of (I), the three remaining hydrogen bonds (entries 5, 6 and 7 in Table 3) are parallel to the molecular planes and define two types of independent coplanar slab, parallel to [201] and running along [010] (Fig. 3, left). These slabs are composed of either type (IA) or type (IB) molecules only. In the case of slab A, two different interactions are operative, having C3A—H3A and C11A—H11A groups as donors, while only the C3B—H3B group is operative in slab B, the remaining contact being too long for any real significance. In all cases, the H-atom acceptors are nitro O atoms. A striking feature is the planar disposition of this juxtaposition of slabs into a common [201] substructure, even in the absence of any `in-plane' hydrogen-bonding interaction directly connecting the slabs. The planarity of these substructures (mean deviation from the least-squares plane = 0.214 Å) can be seen in Fig. 3 (right), which shows them side-on.
In (II), the replacement of an active nitro group by an almost inert trifluoromethyl group changes the type of hydrogen-bonded substructure generated. There is only one `in-plane' intermolecular C—H···O hydrogen bond, also having the fully engaged keto O1 atom as acceptor, which joins pairs of inversion-related molecules and gives rise to weakly bound dimeric units. These dimers act as elemental packing elements in the structure (Fig. 4a). As already noticed in (I), the dimers assemble into planar substructures, this time parallel to [211] (Fig. 4b), with a mean deviation from the least-squares plane of 0.121 Å. Currently, we cannot find any obvious explanation for this particular orientational preference, since it seems that there are no direct interactions between units, at least of the usual type herein discussed.
The reasons behind the two drastically different hydrogen-bonding schemes, viz. the presence/absence of active hydrogen-bonding acceptors, are not applicable to π–π bonding, as it derives from two very similar type a nuclei (see Scheme 1). And, in fact, the resulting interactions are very alike, as Fig. 5 and Table 4 suggest. However, the way in which they complement the above hydrogen-bonded structures gives rise to different supramolecular organizations.
In (I), π–π bonds connect molecules in a (IA)···(IA), (IB)···(IB) and (IA)···(IB) fashion, `mixing' them as shown in Fig. 5(a). These stacking interactions define columns embedded in the [001] plane, but running in different directions according to their z coordinate, viz. [110] for z ~0 or [110] for z ~0.5 (see Figs. S1a and S1b in Supporting information). This `criss-cross' disposition of π-bonded columns provides an (indirect) linkage between the coplanar hydrogen-bonded slabs, resulting in a fully integrated three-dimensional structure.
In the case of (II), the supramolecular structure results from the stacking of hydrogen-bonded dimers along [100], generating columnar arrays (see Figs. S2a and S2b in Supporting information). Neighbouring one-dimensional substructures further interpenetrate along the b axis to form broad two-dimensional structures parallel to [001] (see Fig. S2c in Supporting information).
Summarizing, (I) and (II) are examples of very similar molecular units giving rise to similar weak intermolecular interactions, but their minor molecular differences lead in a subtle way to extremely different supramolecular organization.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
