Pyrimidine-2,4-dithiol [HL 1 = (HS)2C4H2N2] and pyridine-2-thiol [HL 2 = (HS)C5H4N] form the osmium clusters [{Os3(µ-H)(CO)10}2(µ-S2C4H2N2)] and [Os3(µ-H)(CO)10(µ-SC5H4N)], each of which contain chelating µ,η1-thiolate ligands and hydride bridges across common edges of the osmium triangles. In the former complex two osmium triangles are linked together by the pyrimidinedithiolato ligand.

Abstract Tris-thiobenzoates, Arsenic, Antimony, Bismuth Tris-thiobenzoates of arsenic, antimony and bismuth, M(SOCR)3 have been obtained from their oxides and characterized. In the X-ray crystal structure determinations of these, the group 15 atom and the three covalently bonded sulfur atoms are found to constitute a trigonal pyramid, the central atoms lie at a C3 axis. In the bismuth complex the thiobenzoate ligand tends to chelate. However, three comparatively short intermolecular M···S interactions are significant features for these molecules resulting in stacking of trigonal prisms providing an essentially six coordinate environment around arsenic and antimony and a nine-coordinate one for bismuth. The structure of PhSb(SOCPh)2 can be considered
