trans-Influence of Triphenyl Stibine. Crystal and Molecular Structures of cis-[PtCl2(SbPh3)2] and trans-[PtI2(SbPh3)2]
Crystals of cis-[PtCl2(SbPh3)(2)] (1) are monoclinic, space group P2(1)/a with a = 20.5708(12), b = 10.1942(4), c = 33.3984(15) Angstrom, beta = 94.394(4)degrees and Z = 8. Substitution of chloride for iodide yields trans-[PtI2(SbPh3)(2)] (2), the crystals of which are monoclinic, space group P2(1)/c with a = 18.108(4), b = 10.102(2), c = 19.1 15(5) Angstrom, beta = 95.241(16)degrees and Z = 4.
