%X 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 A&#299;, a 15.018(5), b 25.937(9), c 22.722(8) &#506;; &#945; 104.16(2)°, &#946; 115.80(2)°, &#947; 88.65(2)°, Z4.     The diffraction data (Mo K&#945;; 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 &#506;), only four of the six phosphorus ligand atoms being coordinated. This stereochemistry is preserved in solution. A discussion of the metal-phosphorus bond in low-valent metal complexes is provided, it being concluded that &#960;- bonding effects on bond lengths have been overemphasized in the past.
