The carbanions resulting from the deprotonation by n-BuLi of compounds of the type (M=Cr, Mo or W) are readily organomercurated by RHgCl to give neutral complexes of the type >.The X-ray crystal structure of the complex with M=Cr and R=Me has been determined, and reveals intermolecular C-H...O hydrogen bonding interactions to carbonyl oxygen acceptor atoms and a weak secondary intermolecular interaction between a carbonyl oxygen and the mercury atom.Keywords: Chromium; Molybdenum; Tungsten; Carbonyl; Bis(diphenylphosphino)methane; Carbanions
