A Novel Copper Cobalt Inorganometallic Cluster. Synthesis, Structure and Bonding Analysis of Cu3{í2-(CCHCo2(CO)6)}3

Abstract

The reaction of the organometallic carboxylic acid HOOCCCHCo2(CO)6 with copper(II) methoxide leads to a new inorganometallic cluster; Cu3{í2-(CCHCo2(CO)6)}3. This cluster has a triangular core of copper(I) centers surrounded by three CCHCo2(CO)6 fragments. The structure of the cluster has short Cu-Cu and Cu-Co distances (average 2.500 and 2.540 Å, respectively). DFT calculations provide a rationalization of the peculiar bonding in this cluster.
