Abstract

The reactivity of mixed [organohydrazido(1-)][organohydrazido(2-)]molybdenum(VI) complexes [Mo(NHNRPh)(NNRPh)(acac)X2] {R = Ph, X = Br (1); R = Ph, X = I (2) and R = Me; X = I (3)} with tertiary phosphines as PPh3, PMePh2 and PMe2Ph are examined. The syntheses of [Mo(NNPh2)2Br2(PPh3)] (4), [Mo(NNPh2)2Br2(PMePh2)2] (5), [Mo(NNPh2)2Br2(PMe2Ph)2] (6), [Mo(NNPh2)2(acac)I(PPh3)] (7), [Mo(NNPh2)2(acac)(PMePh2)2]+I- (8) and [Mo(NNMePh)2(acac)(PMePh2)2]+I- (9) are reported. All complexes were characterized by elemental analysis, UV-visible, IR, 1H and 31P{H} NMR spectroscopy.
