The reaction of the dialkylchloroborane BClR2 with a Group 6 pentacarbonyl(cyano)metallate(0) in CH2Cl2 or PhMe gives the thermally stable complexes .Crystalline 2a has a linear Cr-C-N-B skeleton with long Cr-C and B-N bonds and a short C-N bond, consistent (as are the IR, Raman and NMR spectra) with its formulation as <(OC)5<*>-C<*><*>-BR2>.Key words: Group 6; Boron; Silicon; Crystal structure; Isocyanide; Carbonyl
