A series of novel (C^N) cyclometallated Au(III) complexes of general formula [Au(py-H)LL] (py-H = C^N cyclometallated 2-benzylpyridine, L and L being chlorido, phosphane or glucosethiolato ligands, n = 0 or 1) have been synthesized and fully characterized using different techniques, including NMR, IR and far-IR, mass spectrometry, as well as elemental analysis. The crystal structure of one comp...

The reaction of the imidazolyl-4(5)-phosphane ligands 2-isopropylimidazol-4(5)yl-diphenylphosphane (4-MIP(iPr)) and tris(2-isopropylimidazol-4(5)yl)phosphane (4-TIP(iPr)) towards gold(I) has been explored and compared to those of analogous 1-methylimidazol-2-ylphosphane ligands. The structure of [(4-MIP(iPr))AuCl] () shows a linear P-Au-Cl coordination, whereas the 4-TIP(iPr) ligand forms a din...

The title compound, [Cu(C5H5NO2S2)(C18H15P)2]·CHCl3, features a tetra-hedrally coordinated CuI atom within a P2S2 donor set defined by two phosphane P atoms and by two S atoms derived from a symmetrically coordinating di-thio-carbamate ligand. Both intra- and inter-molecular hy-droxy-O-H⋯O(hydroxy) hydrogen bonding is observed: the former closes an eight-membered {⋯HOC2NC2O} ring, whereas the l...

The title complex, [PdCl(2)(C(18)H(15)P)(2)]·0.5C(6)H(6), has the Pd(II) ion in a square-planar coordination mode (r.m.s. deviation for Pd, P and Cl atoms = 0.024 Å) with the PPh(3) and Cl ligands mutually trans. The benzene solvent mol-ecule is located about a crystallographic inversion centre. The title complex is isostructural with trans-dichloridobis(triphenyl-phosphane)-palladium(II) 1,4-d...

In the mononuclear mixed-ligand title complex, [AgCl(C7H7NS)(C18H15P)2], the Ag(I) ion is four coordinated by one S atom of a benzene-carbo-thio-amide ligand, two P atoms of two tri-phenyl-phosphane ligands and one chloride ion, displaying a distorted tetra-hedral coordination geometry. In the crystal, pairs of N-H⋯Cl hydrogen bonds form inversion dimers. An intra-molecular N-H⋯Cl hydrogen bond...

In the title Cu(I) compound, [Cu(C6H5N5)(C18H15P)2]BF4, the Cu(I) cation is N,N'-chelated by a 5-(pyridin-2-yl)-1H-tetra-zole ligand and coordinated by two triphenyl-phosphane ligands in a distorted tetra-hedral geometry. The tetra-zole and pyridine rings are essentially coplanar [dihedral angle = 4.1 (3)°]. The tetra-fluoridoborate anion links to the complex cation via an N-H⋯F hydrogen bond.

Synthesis of the first P(V)-bridged bis(NHC) ligand 7 was achieved via deprotonation of P(V)-functionalized bis(imidazolium) salt 6, which was obtained via oxidative desulfurization of bis(imidazole-2-thion-4-yl)phosphane 2. Bis(imidazolium) salt 6 was also employed to synthesize the corresponding silver complex 8. All new products were firmly established by spectroscopic and spectrometric meth...

The crystal structure of the title compound, [Re6Se8{NCC(CH3)3}(Et3P)5](SbF6)2·NCC(CH3)3, contains a face-capped octa-hedral [Re6(μ3-Se)8](2+) cluster core. The pseudo-centrosymmetric [Re6Se8](2+) cluster core is bonded through the Re atoms to five tri-ethyl-phosphane ligands and one tri-methyl-aceto-nitrile ligand. No significant interactions are observed between the cationic cluster, the SbF6...
