Five coordinate complexes of the type Rh(SnCl3)(NBD)L2

Several new rhodium complexes of general formulation Rh(SnCl3)(NBD)L2 (L=P(OMe)3, P(OMe)2Ph, P(OMe)Ph2, P(OEt)3, P(OEt)2Ph, P(OEt)Ph2, P(O-i-Pr)3, P(OPh)3) have been prepared and characterized by elemental analysis and by i.r. and n.m.r. spectroscopy. The complexes show low or no conductivity in acetone solution and react with carbon monoxide (1 atm).
