Chiral platinum(II) complexes. Crystal and molecular structures of cis-[PtPhCl((R, R,)-CHIRAPHOS)] and cis-[PtCl_2((R, R)-CHIRAPHOS)]

摘要

The reaction between trans-PtPhCl(SMe_2)_2 and (R,R)-CHIRAPHOS gives cis-[PtPhCl((R,R)-CHIRAPHOS)] (1). The crystals of which are monoclinic, space group P2_1 with a = 12.875(3), b = 18.012(4), c = 13.864(3)A, #beta# = 109.71(3)° and Z = 4. In CDCl_3 1 reacts with Ph_2P(C_6H_4)CH_2N(Me)(COEt) to give cis[PtCl_2((R, R)-CHIRAPHOS)] (2), the crystals of which are monoclinic, space group P2_1 with a = 7.8052(16), b = 17.679(4), c = 9.843(2)A, #beta# = 100.67(3)° and Z = 2.
