Crystal and molecular structure of cyclopentadienyl(trimethyl)platinum(IV), (π-C5H5)PtMe3

Abstract

The crystal structure of (π-C₅H₅)PtMe₃ has been determined by single-crystal X-ray diffraction methods. Crystals are orthorhombic with a= 11·631, b= 7·180, and c= 10·359 Å, space group Pna2₁. The final value of R is 7·5% for 767 independent reflections. The platinum atom lies above a point approximately in the centre of the five-membered ring. No disorder was detected in the positions of the carbon atoms. Some mean bond lengths are Pt–C(Me) 2·11, Pt–C(π-C₅H₅) 2·32, and C(π-C₅H₅)–C(π-C₅H₅) 1·43 Å.
