Abstract
The reactions of organomercury halides HgR′(Cl)(R′= Me, Et, But or Ph) with complexes of the type [Pt(dmphen){(Z)-RO2CCHCHCO2R}](dmphen = 2,9-dimethyl-1, 10-phenanthroline; R = Me, Et or But) have been studied. The dmphen ligand with suitable ‘in-plane’ steric hindrance stabilizes five-co-ordinate adducts of general formula [PtCl(HgR′)(dmphen){(Z)-RO2CCHCHCO2R}] when R′= alkyl. An influence of the nature of the Hg–bound hydrocarbyl group on the reaction course is observed. Thus, a cluster containing the Pt–Hg–Pt sequence was obtained when R′= Ph or Cl. The molecular structure of [PtCl(HgMe)(dmphen){(Z)-MeO2CCHCHCO2Me}][space group P21/c; a= 13.079(2), b= 13.167(2), c= 15.495(3)Å and β= 94.18(2)°] reveals a large trans influence of the organomercury fragment.Keywords
