Synthesis of Cluster Derivatives Containing the MRuCoSe (M=Mo or W) Core

Abstract

The new clusters [MRuCo(CO)₈(µ₃-Se){η⁵-C₅H₄C(O)OEt}](M=Mo 2 or W 3) are isolated from the reaction of [RuCo₂(CO)₉(µ₃-Se)] 1 and [M(CO)₃{η⁵-C₅H₄C(O)OEt]^–(M=Mo or W), and the structure of cluster 2 has been established by single crystal X-ray diffraction methods.
