Synthesis and structures of tetranuclear rhenium–cobalt mixed metal sulfide clusters [Re3CoS4Cl6(PMe2Ph)4]
摘要:
An isomeric pair of the title compounds have been prepared and characterized by NMR spectroscopy and X-ray crystallography, The major isomer contains three dimethylphenylphoshine ligands coordinated to rhenium atoms in the direction of the mu(3)-S atom in the starting trinuclear rhenium cluster complex, whereas the minor isomer has a dimethylphenylphosphine ligand in the opposite direction. The temperature of the preparative reactions controls the orientation of the phosphine ligands. (C) 2004 Elsevier Ltd. All rights reserved.
