Crystal structure of bis-[1,3-bis-(di-phenyl-phosphan-yl)propane-κ(2) P,P']platinum(II) dichloride chloro-form penta-solvate.

In the title compound, [Pt{Ph2P(CH2)3PPh2}2]Cl2·5CHCl3, the Pt(II) cations, located on a centre of inversion, is coordinated by two chelating diphosphane ligands in a geometry which is close to square-planar. The chelate rings adopt a chair conformation. The Pt(II) cations are arranged in layers separated by Cl(-) anions as well as CHCl3 solvent mol-ecules. While this complex has been reported previously [Anderson et al. (1983 ▶). Inorg. Chim. Acta, 76, L251-L252], this is the first time a structure has been determined.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
