Monoimido complexes of chromium(v) have been obtained by chlorination of CrVI(NBut)2Cl2 to give an oil, ‘Cr(NBut)Cl3,’ which on dissolution in tetrahydrofuran (thf) or dimethoxyethane and crystallising or by interaction with nitrogen or phosphorus ligands gives adducts of stoichiometry Cr(NBut)Cl3L2, e.g. L = thf, quinuclidine, PMe3, etc.; the X-raystructure of Cr(NBut)Cl3(EtPh2P)2 shows the six-coordinate
