The title compound, [Bi(C9H6NS2)3], was prepared by reacting BiCl3 and 2-mercapto-4-phenyl­thia­zole (LH) at room temperature in a stoichiometric ratio of 1:4. The mol­ecular structure reveals a slightly distorted square-pyramidal environment around the BiIII atom. Two of the three monoanionic ligands L coordinate in an N,S-bidentate mode, while one shows a monodentate mode through an S atom. There are no significant inter­molecular inter­actions present in the crystal.

Structure description

For general background on this type of bis­muth chemistry with S- or (N,S)-donor ligands, see: Diemer et al. (1995[Diemer, R., Dittes, U., Nuber, B., Seifried, V., Opferkuch, W. & Keppler, B. K. (1995). Met.-Based Drugs, 2, 271-292.]); Stavila et al. (2006[Stavila, V., Davidovich, V. L., Gulea, A. & Whitmire, K. H. (2006). Coord. Chem. Rev. 250, 2782-2810.]); Briand et al. (2000[Briand, G. G., Burford, N. & Cameron, T. S. (2000). Chem. Commun. pp. 13-14.]). The coordination chemistry of bis­muth with thio­urea or thio­semicarbazide ligands has been studied in detail (Battaglia & Corradi, 1981[Battaglia, L. P. & Corradi, A. B. (1981). J. Chem. Soc. Dalton Trans. pp. 23-26.],1983[Battaglia, L. P. & Corradi, A. B. (1983). J. Chem. Soc. Dalton Trans. pp. 2425-2428.]; Battaglia et al., 1992[Battaglia, L. P., Corradi, A. B. & Pelosi, G. (1992). J. Crystallogr. Spectrosc. Res. 22, 275-279.]). While thio­urea ligands have been found to be S-donor ligands only, thio­semicarbazide shows an (N,S)-coordination mode. Recently, we have reported the coordination modes of three heterocyclic ligands derived from 3-mercapto-4-methyl-1,2,4-triazole (L1H), 2-mercapto-benzimidazole (L2H) and 2-mercapto-4-methyl­thia­zole (L3H), respectively, towards bis­muth(III). In the corresponding three bis­muth complexes [Bi(L1)4(Cl)2]Cl, [Bi(L2)4Cl2]+[Bi(L2)2Cl4] and [Bi(L3)2Cl2(μ-Cl)]2 (Imran et al., 2013[Imran, M., Neumann, B., Stammler, H.-G., Monkowius, U., Ertl, M. & Mitzel, N. W. (2013). Dalton Trans. 42, 15785-15795.], 2014[Imran, M., Neumann, B., Stammler, H.-G., Monkowius, U., Ertl, M. & Mitzel, N. W. (2014). Dalton Trans. 43, 1267-1278.]), all these ligands coordinate solely via their S-donor atoms despite a possible (N,S) coordination.

In the title compound, the deprotonated ligand L (LH is 2-mercapto-4-phenyl thia­zole) exhibits both monodentate S- and bidentate (N,S)-coordination modes (Fig. 1[link]). Two ligands coordinate in a bidentate fashion (via N1, S1, and via N2, S3) while the third one exhibits a monodentate mode via the S5 donor atom, resulting in a slightly distorted square-pyramidal coordination environment. The Bi—N and Bi—S bonds differ in lengths with the Bi—S bonds shorter by ≃ 0.2 Å (Table 1[link]) but the index parameter (Addison et al., 1984[Addison, A. W., Rao, T. N., Reedijk, J., van Rijn, J. & Verschoor, G. C. (1984). J. Chem. Soc. Dalton Trans. pp. 1349-1356.]) of τ5 = 0 indicates an ideal value for a square-pyramidal coordination (ideal value for trigonal–bipyramidal coordination is τ5 = 1).

Synthesis and crystallization

The title compound was prepared by reacting BiCl3 (1 mmol, 0.315 g) and 2-mercapto-4-phenyl thia­zole (LH) (4 mmol, 0.773 g) in THF at room temperature. After stirring for 4 h, the resulting yellow solution was concentrated, yielding a yellow solid that was separated by deca­ntation and washed with small amounts of THF followed by diethyl ether. The solid was dried and recrystallized from a mixture of THF/pentane (ratio v:v = 1:3). Yellow to orange crystals suitable for X-ray diffraction were obtained by slow evaporation of the THF solution of the complex. Yield 76%; m.p. 507 K. 1H NMR (CDCl3): δ 7.58–7.60 (dd, 2H, C2H, C6H), 7.42–7.49 (m, 3H, C3H—C5H), 6.78, CH-thia­zole ring); 13C NMR (CDCl3): δ 188.5 (C9), 142.5 (C8), 129.9 (C2,6), 129.4 (C3,5), 128.1 (C4), 125.9 (C1), 108.9 (C7).

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