Cluster chemistry. Synthesis and X-ray structure of [Ru5(CO)14(CNBut)2], containing an unusual open Ru5 cluster
Abstract
Moderate heating converts [Ru3(CO)11(CNBut)] into [Ru5(CO)14(CNBut)2], which has been shown by X-ray crystallography to contain an open ‘swallow’ cluster with one isocyanide ligand acting as a 6e donor, and bonded to all five metal atoms.
