Crystal and molecular structure of chloro[1-(diphenylphosphino)-3,3,3-trifluoropropen-2-olato](ethoxydiphenylphosphine)palladium(II)–dichloromethane

Abstract

Crystals of the title compound formed via the controlled hydrolysis of cis-[PdCl₂(Ph₂PC:CCF₃)₂] are orthorhombic, space group Pbca with a= 16.982(11), b= 18.312(12), c= 20.774(15)Å, Z= 8. The structure was determined from diffractometer data by Patterson and Fourier syntheses and refined by full-matrix least-squares methods to R 0.058 for 3 799 observed reflections. The palladium atom is co-ordinated in distorted square-planar fashion by a chloride ion, an ethoxydiphenylphosphine, and the phosphorus and oxygen atoms of deprotonated [1-(diphenylphosphino)-3,3,3-trifluoropropen-2-ol]. The diphenylethoxyphosphine phosphorus is trans to the oxygen atom of the chelating ligand. Metal–ligand bond distances are: Pd–Cl(1) 2.356(2), Pd–P(1) 2.222(2), Pd–P(2)2.246(2), and Pd–O(2)2.099(5)Å. Delocalisation over the PC₂O fragment of the chelate ring is indicated by the distances: P(2)–C(1) 1.776(8),C(1)–C(2)1.36(1), and C(2)–O(2) 1.313(9)Å.
