The spontaneous formation of the heteroligated complex [PtCl(κ 2-Ph2PCH2CH2SMe)(Ph 2PCH2CH2SPh)]-Cl (8a) by a novel ligand rearrangement process has been observed. By using the w

A series of novel functionalized phosphines of hemilabile character, R 2P(CH2)nZ, have been prepared from diarylphosphines using several synthetic methodologies. The synthetic methods include the alkylation of lithium diar

Nickel cyanide complexes of the types [Ni(CN)2(ligand)2] and [Ni(CN)2(ligand)3] derived from the four hybrid bidentate ligands 1-(2′-pyridyl)-2-(diphenylphosphino)ethane, 1-(thiomethyl)-2-(diphenylphosphino)ethane, 1-(thioethyl)-2-(diphenylphosphino)ethane, and 1-(thiophenyl)-2-(diphenylphosphino)ethane are described. The complexes [Ni(CN)2(ligand)2] can be four- or five-coordinate. In the first case the bidentate ligands act as monodentate groups by bonding only through phosphorus donor atoms, whereas in the five-coordinate complexes both mono- and bidentate types of coordination of the ligands are involved. The complexes [Ni(CN)2(ligand)2] in solution can react with an excess of ligand to give five-coordinate species of the type [Ni(CN)2(ligand)3], in which only the phosphorus end of the ligand is bonded to the metal atom. The coordination number and stereochemistry of the complexes have been established on the basis of spectroscopic, conductivity, and molecular weight measurements. With the ligands containing phosphorus and sulfur, five-coordinate cationic complexes of formula [Ni(CN)(ligand)2]+ are also obtained, for which, on the basis of the visible spectra, a square-pyramidal structure is proposed.
