Benzophenone imine [M (η1 -NH {double bond, long} CPh2) (CO)n P5 - n] BPh4 [M = Mn, Re; n = 2, 3; P = P(OEt)3, PPh(OEt)2, PPh2OEt, PPh3] complexes were prepared by allowing triflate M (κ1 -OTf) (CO)n P5 - n compounds to react with an excess of the imine. Hydride-imine [MH (η1 -NH {double bond, long} CPh2) P4] BPh4 (M = Ru, Os), triflate-imine [Os (κ1 -OTf) (η1 -NH {double bond, long} CPh2) P4] BPh4 and bis(imine) [Ru (η1 -NH {double bond, long} CPh2)2 P4] (BPh4)2 [P = P(OEt)3] derivatives were also prepared. The complexes were characterized spectroscopically (IR, 1H, 31P, 13C NMR) and a geometry in solution was also established. Hydride-benzophenone imine [IrHCl (η1 -NH {double bond, long} CPh2) L (PPh3)2] BPh4and [IrHCl (η1 -NH {double bond, long} CPh2) L (AsPh3)2] BPh4 [L = P(OEt)3 and PPh(OEt)2] complexes were prepared by reacting hydride IrHCl2 L (PPh3)2 and IrHCl2 L (AsPh3)2 precursors with an excess of imine. Dihydride IrH2 (η1 -NH {double bond, long} CPh2) (PPh3)3 complex was also obtained and a geometry in solution was proposed.
