An X-ray analysis of single crystals of bis[1,1,1- tris(diphenylphosphinomethyl)ethane]platinum(O) is described. The crystals are triclinic, space group Aī, a 15.018(5), b 25.937(9), c 22.722(8) Ǻ; α 104.16(2)�, β 115.80(2)�, γ 88.65(2)�, Z4. ��� The diffraction data (Mo Kα; automatic diffractometry) have provided all atomic positions (with the exception of hydrogen atoms) and the scattering model has been refined by least-squares methods to R 0.084 (4774 independent reflections). The platinum has a distorted tetrahedral stereochemistry (with mean Pt-P 2.287 Ǻ), only four of the six phosphorus ligand atoms being coordinated. This stereochemistry is preserved in solution. A discussion of the ..
