The reaction of Co₂(CO)₈ with EtSPCl₂ gives a new crystal like compound Co₇(μ₇-S)(μ₄-PSEt)(μ-SEt)₂(μ-CO)₂(CO)₁₂,whose structure has been determined by single crystal x-ray diffraction.This special compound reveals some new features in cluster chemistry¹:The fragmentation of a ligand precursor EtSPCl₂ yieldsthree kinds of fragments,μ₇-S,μ₄-PSEt and μ-SEt,which are ligands in the same cluster molecule.There is a new type of bridging S presented——A μ₇-S atom is interspaced into seven Co core.
