Dithiomethylester complexes of ruthenium: crystal structures of η2-dithiomethylestercarbonyltolylisocyanidebis (triphenylphosphine)-ruthenium(II) perchlorate, [Ru(η2-CS2Me) (CO) {CN(p-tolyl) } (PPh3)2]-ClO4·CHCl3·H2O, and η2-dithiomethylesterdicarbonylbis (triphenylphosphine) ruthenium(II) perchlorate, [Ru(η2-CS2Me) (CO)2 (PPh3)2]-ClO4·C6H12

摘要: Abstract Three-dimensional structures of the title compounds have been investigated by conventional x-ray methods using data collected on an automatic diffractometer. Crystals [Ru(η2-CS2Me) (CO) {CN(p-tolyl) } (PPh3)2]-ClO4· built 1 2 CHCl3· bulit H2O are orthorhombic, a = 20.690(4), b 16.118(3), c 15.087(2) A Z 4, space group Pna21 or Pnma. The two triphenylphosphine ligands approximately mirror related, while all remaining atoms cation lie close to, on, equatorial plane. It has not proved possible to differentiate between real and false planes thus distinguish groups. perchlorate ion chloroform water molecules disordered. analysis established that dithioester ligand is coordinated through carbon unmethylated sulphur atoms.
