Steric control of aggregation in neutral silver(I) thiolates, [AgSR]n. Crystal and molecular structures of [AgSCH(SiMe3)2]8, a discrete molecular biscycle of weakly interacting [AgSCH(SiMe3)2]4 units, and of [AgSC(SiPhMe2)3]3 and [AgSC(SiMe3)3]4, discrete molecular monocycles containing linearly coordinated silver(I) and doubly bridging mercapto sulfur donors from novel sterically hindered thiolate ligands. A comparison with the nonmolecular structure of [Ag4{SCH2(SiMe3)}3]n1

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.
