Crystal and molecular structure of cis-Dichlorobis(triphenylphosphite) Platinum(II)

The single crystal structure of cis-dichlorobis(triphenyphosphite) platinum(II), [PtCl2(P(OPh)3)2] has been determined. This complex crystallises in the orthorhombic space group, P212121 with cell constant, a=10.4135(13), b=14.0635(16), c=23.505(3) Ǻ and v=3448.3(7) Ǻ 3. The Pt-Cl1 and Pt-Cl2 distances are 2.3390(10) Ǻ and 2.3256 Ǻ, which are longer than Pt-P1 and Pt-P2 with 2.1985(12) Ǻ and 2.1998(10) Ǻ respectively. These data together with bond angles suggest a distorted square planar geometry for this complex with two chlorine ligands in a cis configuration
