The coordination chemistry of manganese. : Part VII. The preparation and spectroscopic characterisation of some manganese(II) complexes of triphenylphosphine of unusual stoicheiometry, Mn(PPh 3)X 2

Abstract

Novel manganese(II) complexes of triphenylphosphine, Mn(PPh 3)X 2(X = Cl, Br, I, NCS), have been isolated and studied by a number of spectroscopic techniques. The basic structure in the solid state is pseudotetrahedral and the complexes may be oligomeric. The Mn(OPPh 3)(NCS) 2 complex, synthesised for comparative purposes, differs from Mn(PPh 3)(NCS) 2 in a number of important ways.
