Synthesis of clusters containing the OsCoMoS core

Abstract

Several new chiral tetrahedral clusters containing the OsCoMoS core were synthesised by the thermal reaction of the precursor [(μ 3-S)OsCo2(CO)9] with the functionally-substituted metal exchange reagents [Mo(CO)3(C5H4)R][(R=CHO, C(O)CH3, C(O)C6H4-1,4-CO2Me)]. The structure of cluster [(μ 3-S)OsCoW(CO)8C5H4C(O)CH3] was established by X-ray single crystal diffraction.
