Synthesis and X-ray crystal structure of cis-[PdCl2{Ph2PCH2CH2P(CF3)2}][cis-1-bistrifluoromethylphosphino-2-(diphenylphosphino)ethane]dichloropalladium(II)
Abstract
A novel unsymmetrical ditertiary phosphine, Ph2PCH2CH2P(CF3)2, and its chelate complex cis-[PdCl2{Ph2PCH2CH2P(CF3)2}] have been prepared and characterised; the molecular structure of the latter compound shows that the organic substituents on the phosphorus atoms exert a profound effect on the metal–ligand bonding and that the trans-influence of the PPh2 group is considerably greater than that of the P(CF3)2 group.
