trans-Carbonyl-chlorido-bis-(tri-ethyl-phosphane-κP)platinum(II) tetra-fluorido-borate.

Abstract

The chemical formulation of the title compound was established as trans-[PtCl{P(C₂H₅)₃(CO)}BF₄ by single-crystal X-ray analysis, in contrast to the five-coordinate tetra-fluoro-ethyl-ene complex that had been anti-cipated. The compound had been prepared by reaction of trans-PtHCl(P(C₂H₅)₃)₂ with C₂F₄ in the absence of air, and the presence of the carbonyl group was not suspected. The square-planar cations and BF₄ ^- anions are linked by C-H⋯F and C-H⋯O inter-actions into thick wavy (010) sheets. The present crystal-structure refinement is based on the original intensity data recorded in 1967.
