The crystal and molecular structure of [(PPh3)2Cu(O2CPhOH)]·CH3CH2OH has been determined by X ray crystallography. It crystallizes in the monoclinic system, space group P21/c, with Mr=771.26 (C45H41CuO4P2), a=0.96413(19)nm, b=1.5780(3)nm, c=2.5426(5)nm, β=100.27(3)°, V=3.8065(13)nm3, The title compound consists of discrete copper? bis(triphenylphosphine) salicylate molecules and ethanol solvate. Each Cu is coordinated to two phosphorus atoms of triphenylphosphine ligands and one of carboxylate oxygens in a trigonal planar geometry. In the solid, the intramolecular hydrogen bond and extensive intermolecular interaction connecting (PPh3)2Cu(O2CPhOH) molecules and ethanol solvate form hydrogen bonds network which stabilize the crystal structure.

The crystal structures of the complexes of [Au(Et XA)(PPh3)2] (1), and [Cu(Et XA)(PPh3)2] (2), have been determined by X ray crystallography. They are isomorphous. The crystal structures are very similar and consist of discrete molecules of [Au(Et XA)(PPh3)2] and [Cu(Et XA)(PPh3)2], respectively. They all display distorted tetrahedral geometry around the central metal atom. In the complexes, the ethylxanthate ions act as bidentate ligands with their S atoms coordinated to metal. Each forms a four member chelate ring. The P atoms from two triphenylphosphine ligands are coordinated to the metal atom. The Au P bond lengths are 0.2295(2)nm and 0.2329(2)nm, and the Au S bond lengths are 0.2620(3)nm and 0.2846(3)nm, respectively. The Cu P and Cu S bond lengths are 0.2254(1)nm, 0.2273(2)nm, and 0.2375(1)nm, 0.2495(2)nm, respectively. Elemental analysis, electronic and IR spectra are in agreement with the structural data.

A novel N,N′-dibenzyl-benzimidazolium tetrachlorocuprate(II) complex, 2, was synthesized and its crystal structure was determined by X-ray diffraction. It crystallizes in monoclinic system, space group P2/c, a=1. 203 9(2) nm, b=0.975 0(2) nm, c=1.878 2(6) nm, β=114.12(2)°, V=2.012 2(8) nm3. Its structure was identified by EA, IR and UV spectra and characterized by elec trochemistry, thermal and magnetic property. The Cu(II) atom of 2- has di storted tetrahedral coordination geometry. In the crystal structure, there are s trong extensive C-H…Cl hydrogen bonds and π-π stacking interactions, which st abilized the crystal structure. CCDC: 221570.
