N2 - A range of new cadmium(II) thiosaccharinate (tsac) complexes have been prepared from reactions of the synthon [Cd(tsac)2·H2O] with a variety of two-electron donor ligands including amino- and acetyl-amino heterocycles, 2-mercaptobenzoimidazole, 2-mercaptobenzothiozole and 2-phenylpyridine, as well as the bidentate small bite-angle diphosphane, bis(diphenylphosphino)methane (dppm), and the tridentate ligand 2,6-diacetylamidopyridine (daapH2). Four types of complex have been isolated, namely [Cd(tsac)2L2], [Cd(tsac)2L], [Cd(tsac)2(μ-dppm)]2 and [Cd(tsac)2(κ3-daapH2)(H2O)]. Crystal structures of three, namely [Cd(tsac)(μ-tsac)(κ2-aapH)]2 (aapH = 2-acetylaminopyridine), [Cd(tsac)2(abtH)2] (abtH = 2-aminobenzothiazole) and [Cd(tsac)2(bimsH)2] (bimsH = 2-mercaptobenzimidazole) have been carried out. In all the tsac ligand(s) bind exclusively through coordination of the thiocarbonyl sulfur atom highlighting the chalcogenophilic nature of cadmium. In [Cd(tsac)(μ-tsac)(κ2-aapH)]2 the tsac ligands adopt both bridging and terminal coordination modes, the former being relatively rare.
