Electro-oxidation of tetra­methyl­tetra­thia­fulvalene (TMTTF) in the presence of the chiral anion (1S)-camphor-10-sulfonate (S-camphSO3−) in tetra­hydro­furan/water medium afforded a 1/1 salt formulated as TMTTF·S-camphSO3·2H2O or 2-(4,5-dimethyl-1,3-di­thiol-2-yl­idene)-4,5-dimethyl-1,3-di­thiole radical ion (1+) [(1S)-7,7-dimethyl-2-oxobi­cyclo­[2.2.1]heptan-1-yl]methane­sulfonate dihydrate, C10H12S4+·C10H15O4S−·2H2O. In this salt, two independent TMTTF units are present but, in both cases, the observed bond lengths and especially the central C=C distance [1.392 (6) and 1.378 (6) Å] are in agreement with a complete oxidation of TMTTF which is thus present as TMTTF.+ radical cations. These cations form one-dimensional stacks in which they are associated two by two, forming dimers with short [3.472 (1) to 3.554 (2) Å] S⋯S contacts. The two S-camphSO3 anions present also form stacks and are connected with each other via the water mol­ecules with many O—H⋯O hydrogen bonds ranging from 1.86 (3) to 2.15 (4) Å; the O—H⋯O hydrogen-bonding network can be described as being constituted of C22(6) chains bearing R33(11) lateral rings. On the other hand, the columns of cations and anions are connected through C—H⋯O hydrogen bonds, forming a system expanding in three directions; finally, the result is a three-dimensional network of O—H⋯O and C—H⋯O hydrogen bonds.

1. Chemical context

Chiral mol­ecular conductors may display inter­esting properties such as the magneto-chiral anisotropy effect; the different strategies of access to these materials have been recently reviewed (Avarvari & Wallis, 2009[Avarvari, N. & Wallis, J. D. (2009). J. Mater. Chem. 19, 4061-4076.]; Pop et al., 2014[Pop, F., Auban-Senzier, P., Canadell, E., Rikken, G. L. J. A. & Avarvari, N. (2014). Nat. Commun. 5, 3757.]). Among these possible strategies, a straightforward a priori approach consists of combining, through electrocrystallization experiments, chiral counter-anions, existing in enanti­opure form, to TTF-based radical-cations; in this context, due to the commercial availability of the parent acid S-camphSO3H, the anion S-camphSO3− appears to be a ready choice and, in fact, it has already been used to obtain the salt (EDT-TTFI2)2·S-camphSO3·H2O, where EDT-TTFI2 is di­iodo­ethyl­enedi­thiotetra­thia­fulvalene (Brezgunova et al., 2010[Brezgunova, M., Shin, K. S., Auban-Senzier, P., Jeannin, O. & Fourmigué, M. (2010). Chem. Commun. 46, 3926-3928.]). In addition, it is worth mentioning a more general review relating to conducting radical cation salts with organic anions, especially anions derived from carb­oxy­lic and sulfonic organic acids (Geiser & Schlueter, 2004[Geiser, U. & Schlueter, J. A. (2004). Chem. Rev. 104, 5203-5242.]).

2. Structural commentary

The title compound crystallizes with two independent TMTTF cations, two independent S-camphSO3 anions and four water mol­ecules (Fig. 1[link]) in the asymmetric unit. The geometries of the two types (A and B) of TMTTF units (Fig. 1[link]), are rather similar despite the fact that A and B are crystallographically independent; in both case, the observed bond lengths (see e.g. Penicaud et al., 1990[Penicaud, A., Batail, P., Coulon, C., Canadell, E. & Perrin, C. (1990). Chem. Mater. 2, 123-132.]; Shibaeva, 1984[Shibaeva, R. P. (1984). Sov. Phys. Crystallogr. 29, 288-289.]) and especially the central C=C distance [1.392 (6) Å in A and 1.378 (6) Å in B] are in agreement with a complete oxidation of TMTTF which is thus present as TMTTF.+ radical-cations, in agreement also with the 1/1 cation/anion balance of this salt.

3. Packing of the donors

The cations form columns along the a axis in which the two types, A and B, of TMTTF units alternate (Fig. 2[link]). The overall arrangement of the donors can be described as mono-dimensional since these stacks are isolated. Starting from one particular column, a set of equivalent columns may be deduced by translation along b, thus generating a cationic layer lying in the ab plane; however, there is no vicinity relation between two successive donors belonging to two different stacks of the same layer, except for proximity of the external methyl groups. When looking in the c-axis direction, successive layers are completely separated by slabs of anions; moreover, the orientation of the donors is different in two consecutive cationic layers since they adopt a herringbone arrangement.

[Figure 2]
Figure 2
Overall view, along the a axis, of the crystal packing.

The packing of the donors within one stack is shown more precisely in Fig. 3[link]. The two alternating mol­ecules (A and B) are nearly parallel, the dihedral angle between their mean planes being only 0.24°. Within a stack, two independent inter­molecular inter­vals alternate with mean inter-plane distances of 3.40 and 3.71 Å. One can conclude in favour of the presence of dimers since the four inter­molecular S⋯S contacts corresponding to the smaller inter­val range from 3.472 (1) to 3.554 (2) Å (Fig. 3[link]) and thus are shorter than twice the van der Waals radius of sulfur (3.6–3.7 Å: Bondi, 1964[Bondi, A. (1964). J. Phys. Chem. 68, 441-451.]; Pauling, 1960[Pauling, L. (1960). The Nature of the Chemical Bond, 3rd ed., ch. 7. Ithaca: Cornell University Press.]); within a dimer the A and B units adopt a bond-over-ring (Williams et al., 1992[Williams, J. M., Ferraro, J. R., Thorn, R. J., Carlson, K. D., Geiser, U., Wang, H. H., Kini, A. M. & Whangbo, M. H. (1992). Organic Superconductors, pp. 277-280. Englewood Cliffs: Prentice Hall.]) relative arrangement. On the other hand, all S⋯S distances across the larger inter­val exceed the van der Waals distance, ranging from 4.026 (2) to 4.050 (2) Å.

4. Supra­molecular features

The S-camphSO3 anions stack along the a axis and are connected with each other via the water mol­ecules with many O—H⋯O hydrogen bonds ranging from 1.86 (3) Å to 2.15 (4) Å (Table 1[link]). The oxygen from one sulfonate is linked to the oxygen of the neighbouring sulfonate through a bridg­ing water mol­ecule, while the oxygen of this latter is linked to the H atom of another water mol­ecule, which is also connected to the oxygen of the ketone group, through O—H⋯O inter­actions (Fig. 4[link]). Thus, in Etter's classification (Etter, 1990[Etter, M. C. (1990). Acc. Chem. Res. 23, 120-126.]), the O—H⋯O hydrogen-bonding network can be described as being constituted of C22(6) chains bearing R33(11) lateral rings. On the other hand, the columns of cations and anions are connected through C—H⋯O hydrogen bonds, forming a system expanding in all three directions (Fig. 5[link] and Table 1[link]); finally, the result is a three-dimensional network of O—H⋯O and C—H⋯O hydrogen bonds.

5. Synthesis and crystallization

Synthesis of the supporting electrolyte (1S)-camphor-10-sulfonic acid (Aldrich) (2.32 g, 10 mmol) was dissolved in water (50 ml), then 10 ml of a 1.0 mol l-1 methano­lic solution of tetra­butyl ammonium hydroxide (Aldrich) were added dropwise. This aqueous solution was stirred for one hour then extracted twice with di­chloro­methane (2 × 100 ml). After drying over MgSO4, evaporation of di­chloro­methane afforded tetra­butyl­ammonium S-camphorsulfonate (Bu4N+·S-camphSO3−) (4.50 g, yield 95%), m.p. 410–412 K. Elemental analysis: calculated for C26H51NO4S: C 65.92, H 10.85, N 2.96, S 6.77%; found: C 65.77, H 11.25, N 2.91, S 6.76%.1H NMR (300 MHz, CDCl3): δ 0.82 (3H, s), 1.00 (12H, t, J = 7.3 Hz), 1.15 (3H, s), 1.32 (1H, m), 1.45 (8H, pseudo sextuplet), 1.66 (8H, m), 1.83 (3H, pseudo t), 1.99 (2H, m), 2.29 (1H, m), 2.83 (2H, m), 3.31 (8H, pseudo q).

Electrocrystallization of TMTTF·S-camphSO3·2H2O A conventional H-shaped cell was charged with 142 mg (0.3 mmol) of Bu4N+·S-camphSO3− dissolved in 20 ml of a 98/2 (v/v) tetra­hydro­furan–water mixture, degassed with argon. TMTTF (7.8 mg, 0.03 mmol) was introduced in the anodic arm and was then electro-oxidized under galvanostatic conditions with stepwise increases of the applied current (Anzai et al., 1995[Anzai, H., Delrieu, J. M., Takasaki, S., Nakatsuji, S. & Yamada, J. (1995). J. Cryst. Growth, 154, 145-150.]): 0.5 µA for 3 days, then 1 µA for 4 days, 2 µA for 3 days and finally 5 µA for 8 days; afterwards, the black needles of TMTTF·S-camphSO3·2H2O, deposited at the platinum wire anode, were collected. The electrocrystallization was conducted at room temperature except during the 6 last days during which the cell was cooled to 283 K.

Unsuccessful electrocrystallization experiments Electrocrystallizations, using Bu4N+·S-camphSO3− (or other camphSO3− salts) as supporting electrolyte, were attempted, in various solvent conditions, with the following donors: TTF itself, BEDT-TTF, ethyl­enedi­thio­tetra­thia­fulvalene (EDT-TTF) and tetra­methyl­tetra­selena­fulvalene (TMTSF), without affording usable crystals. Thus, TMTTF·S-camphSO3·2H2O and (EDT-TTFI2)2·S-camphSO3·H2O (Brezgunova et al., 2010[Brezgunova, M., Shin, K. S., Auban-Senzier, P., Jeannin, O. & Fourmigué, M. (2010). Chem. Commun. 46, 3926-3928.]), are presently the only known salts associating the camphorsulfonate anion to TTF donors.

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2[link]. All H atoms attached to C were fixed geometrically and treated as riding with C—H = 0.96 Å (idealized methyl group, torsion angle from electron density), 0.97 Å (methyl­ene) or 0.98 Å (methine), with Uiso(H) = 1.2Ueq(C) or Uiso(H) = 1.5Ueq(meth­yl). The H atoms of the water mol­ecule were located in a difference electron density map and then refined as riding on their parent O atoms with Uiso(H) = 1.5Ueq(O).

Chemical context top

Chiral molecular conductors may display inter­esting properties such as the magneto-chiral anisotropy effect; the different strategies of access to these materials have been recently reviewed (Avarvari & Wallis, 2009; Pop et al., 2014). Among these possible strategies, a straightforward a priori approach consists of combining, through electrocrystallization experiments, chiral counter-anions, existing in enanti­opure form, to TTF-based radical-cations; in this context, due to the commercial availability of the parent acid S-camphSO3H, the anion S-camphSO3- appears to be a ready choice and, in fact, it has already been used to obtain the salt (EDT-TTFI2)2·S-camphSO3·H2O, where EDT-TTFI2 is di­iodo-ethyl­enedi­thio-tetra­thia­fulvalene (Brezgunova et al., 2010). In addition, it is worth mentioning a more general review relating to conducting radical cation salts with organic anions, especially anions derived from carb­oxy­lic and sulfonic organic acids (Geiser & Schlueter, 2004).

Structural commentary top

The title compound crystallizes in the chiral space group P21. The asymmetric unit consists of two crystallographically independent TMTTF cations, two S-camphSO3 anions and four water molecules (Fig.1); thus, owing to the presence of the twofold symmetry axis inherent in the P21 group, the unit cell contains, in fact, four anions, four cations and eight water molecules.

The geometries of the two types (A and B) of TMTTF units (Fig. 1), are rather similar despite the fact that A and B are crystallographically independent; in both case, the observed bond lengths (see e.g. Penicaud et al., 1990; Shibaeva, 1984) and especially the central C=C distance [1.392 (6) Å in A and 1.378 (6) Å in B] are in agreement with a complete oxidation of TMTTF which is thus present as TMTTF.+ radical-cations, in agreement also with the 1/1 cation/anion balance of this salt.

Packing of the donors top

The cations form columns along the a axis in which the two types, A and B, of TMTTF units alternate (Fig. 2). The overall arrangement of the donors can be described as mono-dimensional since these stacks are isolated. Starting from one particular column, a set of equivalent columns may be deduced by translation along b, thus generating a cationic layer lying in the ab plane; however, there is no vicinity relation between two successive donors belonging to two different stacks of the same layer, except for proximity of the external methyl groups. When looking in the c-axis direction, successive layers are completely separated by slabs of anions; moreover, the orientation of the donors is different in two consecutive cationic layers since they adopt a herringbone relative disposition.

The packing of the donors within one stack is shown more precisely in Fig. 3. The two alternating molecules (A and B) are nearly parallel, the dihedral angle between their mean planes being only 0.24°. Within a stack, two independent inter­molecular inter­vals alternate with mean inter-plane distances of 3.40 and 3.71 Å. One can conclude in favour of the presence of dimers since the four inter­molecular S···S contacts corresponding to the smaller inter­val range from 3.472 (1) to 3.554 (2) Å (Fig. 3) and thus are shorter than twice the van der Waals radius of sulfur (3.6–3.7 Å: Bondi, 1964; Pauling, 1960); within a dimer the A and B units adopt a bond-over-ring (Williams et al., 1992) relative arrangement. On the other hand, all S···S distances across the larger inter­val exceed the van der Waals distance, ranging from 4.026 (2) to 4.050 (2) Å.

Supra­molecular features top

The S-camphSO3 anions stack along the a axis and are connected with each other via the water molecules with many O—H···O hydrogen bonds ranging from 1.86 (3) Å to 2.15 (4) Å (Table 1). The oxygen from one sulfonate is linked to the oxygen of the neighbouring sulfonate through a bridging water molecule, while the oxygen of this latter is linked to the H atom of another water molecule, which is also connected to the oxygen of the ketone group, through O—H···O inter­actions (Fig. 4). Thus, in Etter's classification (Etter, 1990), the O—H···O hydrogen-bonding network can be described as being constituted of C22(6) chains bearing R33(11) lateral rings. On the other hand, the columns of cations and anions are connected through C—H···O hydrogen bonds, forming a system expanding in all three directions (Fig. 5 and Table 1); finally, the result is a three-dimensional network of O—H···O and C—H···O hydrogen bonds.

Synthesis and crystallization top

Synthesis of the supporting electrolyte (1S)-camphor-10-sulfonic acid (Aldrich) (2.32 g, 10 mmol) was dissolved in water (50 ml), then 10 ml of a 1.0 mol l-1 methano­lic solution of tetra­butyl ammonium hydroxide (Aldrich) were added dropwise. This aqueous solution was stirred for one hour then extracted twice with di­chloro­methane (2 × 100 ml). After drying over MgSO4, evaporation of di­chloro­methane afforded tetra­butyl­ammonium S-camphorsulfonate (Bu4N+·S-camphSO3-) (4.50 g, yield 95%), m.p. 410–412 K. Elemental analysis: calculated for C26H51NO4S: C 65.92, H 10.85, N 2.96, S 6.77%; found: C 65.77, H 11.25, N 2.91, S 6.76%.1H NMR (300 MHz, CDCl3): δ 0.82 (3H, s), 1.00 (12H, t, J = 7.3 Hz), 1.15 (3H, s), 1.32 (1H, m), 1.45 (8H, pseudo sextuplet), 1.66 (8H, m), 1.83 (3H, pseudo t), 1.99 (2H, m), 2.29 (1H, m), 2.83 (2H, m), 3.31 (8H, pseudo q).

Electrocrystallization of TMTTF·S-camphSO3·2H2O A conventional H-shaped cell was charged with 142 mg (0.3 mmol) of Bu4N+·S-camphSO3- dissolved in 20 ml of a 98/2 (v/v) tetra­hydro­furan–water mixture, degassed with argon. TMTTF (7.8 mg, 0.03 mmol) was introduced in the anodic arm and was then electro-oxidized under galvanostatic conditions with stepwise increases of the applied current (Anzai et al., 1995): 0.5 µA for 3 days, then 1µA for 4 days, 2 µA for 3 days and finally 5 µA for 8 days; afterwards, the black needles of TMTTF·S-camphSO3·2H2O, deposited at the platinum wire anode, were collected. The electrocrystallization was conducted at room temperature except during the 6 last days during which the cell was cooled to 263 K.

Unsuccessful electrocrystallization experiments Electrocrystallizations, using Bu4N+·S-camphSO3- (or other camphSO3- salts) as supporting electrolyte, were attempted, in various solvent conditions, with the following donors: TTF itself, BEDT-TTF, ethyl­enedi­thio­tetra­thia­fulvalene (EDT-TTF) and tetra­methyl­tetra­selena­fulvalene (TMTSF), without affording usable crystals. Thus, TMTTF·S-camphSO3·2H2O and (EDT-TTFI2)2·S-camphSO3·H2O (Brezgunova et al., 2010), are presently the only known salts associating the camphorsulfonate anion to TTF donors.

Refinement top

Crystal data, data collection and structure refinement details are summarized in Table 2. All H atoms attached to C were fixed geometrically and treated as riding with C—H = 0.96 Å (idealized methyl group, torsion angle from electron density), 0.97 Å (methyl­ene) or 0.98 Å (methine), with Uiso(H) = 1.2Ueq(C) or Uiso(H) = 1.5Ueq(methyl). The H atoms of the water molecule were located in a difference electron density map and then refined on their parent O atoms with Uiso(H) = 1.5Ueq(O).

Special details top

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.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. The H atoms on the water molecules were added by Fourier difference map and then restrained with 13 DFIX commands between O and H and H and H on the 4 water molecules.
