Abstract

A series of bis(triorganophosphine)bis(selenocarboxylato)-nickel(II)3, -palladium(II)4 and -platinum(II)5 complexes have been synthesised from the reaction of sodium selenocarboxylates 1 or O-silyl selenocarboxylates 2 with the corresponding bis(phosphine)metal dichloride in good to high yields and have been characterized by 1H, 13C, 31P and 77Se NMR spectroscopy and elemental analysis. Additionally [M(4-MeC6H4COSe)2(PEt3)2](M = Ni 3d, Pd 4d or Pt 5b) have been crystallographically characterized and reveal four-co-ordinate planar structures with each of the two selenocarboxylate and phosphine ligands lying trans. The carbon–oxygen bond lengths [1.209(6), 1.203(8) and 1.212(6)Å] of the selenocarboxylate ligand of 3d, 4d and 5d show values typical of a carbon–oxygen double bond; co-ordination of the carbonyl oxygen to the metal is not observed.
