Abstract

Tungsten trioxide has been found to be a convenient precursor for the synthesis of metal cluster compounds with new types of cluster cores. The reaction between WO3 and KCN led to the formation of the cluster complex [{W64-O)23-CCN)4}(CN)16]10−. Unexpectedly, it includes the fully deprotonated form of acetonitrile, the CCN3− anion, as a μ3-bridging ligand coordinated to the trigonal faces of the bitetrahedral W6 metallocluster. A similar complex [{W64-O)23-As)4}(CN)16]10− containing μ3-As3− ligands instead of μ3-CCN3− ones has been synthesized by the reaction between WO3, As and KCN.
