“…A weak to medium intensity band in the region 246-272 cm À1 has been assigned to m(Bi-S) [14] while a medium to strong intensity band in the region 426-469 cm À1 has been assigned to m(Bi-C) [14]. These derivatives also show medium to strong intensity bands in the region 1427-1438 cm À1 and 1000-1081 cm À1 assigned to m(C@N) and m(C@S) stretching vibrations, respectively, consistent with the biconnective nature of the dithiocarbamate moieties in these complexes.…”

Reactions of methylbismuth(III) dichloride with sodium salts of dithiocarbamates have been carried out in 1:1 and 1:2 stoichiometric ratios in anhydrous benzene to yield products of the types [MeBiCl(S 2 CNR 2 )] [where R = Me (1), Et (2) and i Pr (3)] and,andThese complexes were characterized by elemental analyses and by FT-IR and NMR ( 1 H and 13 C) spectra. The X-ray structure of [MeBiCl(S 2 CNEt 2 )] (2), indicates the presence of unique BiÁ Á ÁClÁ Á ÁBi secondary bonds resulting in a distorted square pyramidal environment around the central bismuth(III) atom. TGA of (6) shows a single step break down of the complex to Bi 2 S 3 at 262.8°C. Transformations of (6) and (8) to pure Bi 2 S 3 have been carried out successfully in refluxing xylene (142°C) as revealed by XRD and SEM studies.

A series of methylbismuth(III)O,O-alkylenedithiophosphates of the type [MeBi{S2P(O-G-O)}2][where G = CH 2 CH(CH 3 ) (1), (CH 2 ) 4 (2), CH 2 CH 2 CH(CH 3 ) (3), CH(CH 3 )CH(CH 3 ) (4), CH 2 CHCH 2 CH 3 (5), CH(CH 3 )CH 2 C(CH 3 ) 2 (6) and C(CH 3 ) 2 C(CH 3 ) 2 (7)] have been isolated by the reaction of methylbismuth(III) dichloride with potassium salt of O,O-alkylenedithiophosphoric acids in 1 : 2 molar ratio in anhydrous benzene. These newly synthesized derivatives were characterized by elemental analyses, FT IR and multinuclear NMR ( 1 H, 13 C and 31 P) spectral studies. Thermogravimetric analysis of 6 has shown a single-step decomposition of complex to Bi 2 S 3 at 154.3 • C. Transformation of 2 and 6 to pure Bi 2 S 3 was carried out successfully at refluxing xylene temperature (142 • C) as revealed by XRD and SEM analyses.
