t-Butylimido Complexes of Chromium(V). X-Ray Crystal Structure of t-Butylimidotrichlorobis(ethyldiphenylphosphine)chromium(V)

Article abstract of DOI:10.1039/c39900001678

Monoimido complexes of chromium(V) have been obtained by chlorination of Cr^IV(NBu^t)2Cl2 to give an oil, 'Cr(NBu^t)Cl3,' which on dissolution in tetrahydrofuran (thf) or dimethyoxyethane and crystallising or by interaction with nitrogen or phosphorus ligands gives adducts of stoichiometry Cr(NBu^t)Cl3L2, e.g.L = thf, quinuclidine, PMe3, etc.; the X-ray structure of Cr(NBu^t)Cl3(EtPh2P)2 shows the six-coordinate compound to have trans phosphine and mer chloro groups.
