Abstract

The intermediately generated Li[(Me3Si)2CHSb(H)] reacts with [(N3N)WCl] to give the first complex with a terminal stibido ligand, [(N3N)WSb] (see structure). Spectroscopic features and the X-ray structure of this product clearly reveal the triple-bond character of the WSb bond. A comparison of the bonding situations in the series [(N3N)WE] (E=P, As, Sb, Bi) indicates only a weak polarization of the triple bond.
