In the crystal structure of the title compound, [Ru(3)(C(9)H(11)P)H(2)(C(18)H(15)P)(CO)(8)], the triangular Ru(3) unit is capped with one mesitylphosphin-idene ligand. In the trigonal-pyramidal Ru(3)P core, one Ru(II) atom is coordinated by a triphenyl-phosphane ligand in a terminal fashion. Two hydride ligands bridge over two Ru-Ru bonds. These Ru-Ru bonds [2.9400 (4) and 2.9432 (4) Å] are sli...

In the title compound, [Rh(C(13)H(16)NO)(C(18)H(15)P)(CO)], the coordination geometry of the Rh(I) atom is square-planar, formed by the coordinating N and O atoms of the bidentate enaminoketonate ligand, one C atom from the carbonyl group and a P atom from triphenyl-phosphine. The complex displays a 0.591 (3):0.409 (3) ratio disorder of the phenyl unit of the monoanionic N,O-bidentate ligand. I...

The title compound, [CuCl(C(3)H(8)N(2)S)(C(18)H(15)P)(2)]·0.5CH(3)CN, was prepared by the reaction of copper(I) chloride with 1,3-dimethyl-thio-urea (dmtu) and triphenyl-phosphine (PPh(3)) in acetonitrile. The Cu(I) atom has a distorted tetra-hedral environment formed by two P atoms from triphenyl-phosphine, one S atom from the dmtu ligand and one Cl atom. In addition, the mol-ecules exhibit in...

In the title solvated salt, [Ag(C18H15P)4](CF3CO2)·C2H5OH, the Ag(I) atom is coordinated by four P atoms from triphenyl-phosphane ligands in a distorted tetra-hedral geometry. The anion and solvent are engaged in weak O-H⋯O hydrogen bonds. Of the four triphenyl-phosphane ligands, two each have an equally disordered phenyl ring while the Ag(I) atom is disordered over two positions in a 0.9595 (1...

The title compound, [Cu(C(16)H(11)BrN(2))(C(18)H(15)P)(2)]BF(4), is composed of one Cu(I) atom, one 6-(4-bromo-phen-yl)-2,2'-bipyridine (L) ligand, two triphenyl-phosphane mol-ecules and one tetra-fluoridoborate anion. The Cu(I) ion is four-coordinated in a distorted tetra-hedral configuration by two N atoms from L and two P atoms from triphenyl-phosphane ligands. In the L ligand, the two pyrid...
