Abstract

Reactions of Sn–S clusters with [IrCl(cod)]₂ afforded an Ir–Sn–S cluster with unprecedented topology, {[Ir₃(cod)₃(μ₃-S)₂](μ₃-S)SnCl}₂, in which two [Ir₃S₂] units and a central [Sn₂S₂] unit are connected via Ir–S and Ir–Sn bonds. Each of the crystallographically independent Ir atoms exhibits a specific chemical environment. Quantum chemical studies shed light on the electronic structure of the multinary cluster and the Ir–Sn bonds.
