The Interaction of Triosmium Clusters with Pyridinethiols: the Crystal and Molecular Structures of [{Os3(µ-H)(CO)10}2(µ-S2C4H2N2)]and [Os3(µ-H)(CO)10(µ-SC5H4N)]

Abstract

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.
