Synthesis and Characterization of µ-Alkyne Molybdenum– and Tungsten–Cobalt Clusters containing Functionally Substituted Cyclopentadienyl Ligands†

Abstract

Eight new µ-alkyne molybdenum– and tungsten–cobalt clusters containing functionally substituted cyclopentadienyl ligands have been synthesized via organic carbonyl transformation reactions of clusters [(η⁵-MeCOC₅H₄)(OC)₂M(µ-C₂Ph₂)Co(CO)₃] (M=Mo or W).
