Chiral platinum(II) complexes. Crystal and molecular structures of cis-[PtPhCl((R,R)-CHIRAPHOS)] and cis-[PtCl2((R,R)-CHIRAPHOS)]

The reaction between trans-PtPhCl(SMe2)2 and (R,R)-CHIRAPHOS gives cis-[PtPhCl((R,R)-CHIRAPHOS)] (1). The crystals of which are monoclinic, space group P21 with a=12.875(3), b=18.012(4), c=13.864(3) Å, β=109.71(3)° and Z=4. In CDCl31 reacts with Ph2P(C6H4)CH2N(Me)(COEt) to give cis[PtCl2((R,R)-CHIRAPHOS)] (2), the crystals of which are monoclinic, space group P21 with a=7.8052(16), b=17.679(4), c=9.843(2) Å, β=100.67(3)° and Z=2.
