COMPLEXES OF GOLD(I) AND PLATINUM(II) WITH POLYAROMATIC PHOSPHINE-LIGANDS

Gold and platinum(II) complexes of the phosphine ligands PArnPh3-n (Ar = naphthyl, anthracenyl, ferrocenyl and other polyaromatic groups) ha ve been synthesised. The electron donating abilities of naphthyl and a nthracenyl phosphine ligands has been explored using gas phase photoel ectron spectral data on the parent phosphines and their relative compl exing ability to platinum precursor molecules has been assessed by mea ns of synthetic studies and NMR experiments. Their steric parameters h ave been estimated by the Tolman cone angle methodology using X-ray cr ystallographic data. The molecular structures of the gold complexes [A uCl(PAn(2)Ph)]. CHCl3 and [Au(PFc(2)Ph)(2)]. CHCl3 have been determine d. (C) 1998 Elsevier Science S.A.
