The synthesis of tetrahedral clusters SOsCo2(CO)9, relevant to chiral tetrahedral clusters containing the SOsCoW core

Abstract

A simple route to synthesise clusters [SOsCo2(CO)9] in excellent yield and mild reaction conditions is described. Several new chiral tetrahedral clusters containing the Os element were synthesised by the thermal reaction of the precursor [(μ3-S)OsCo2(CO)9] with the functionally-substituted metal exchange reagents. The structure of cluster [(μ3-S)OsCoW(CO)8C5H4C(O)CH3] was established by X-ray single crystal diffraction.
