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 and molecular structure of ·(ClO4)2 has been determine d by X-ray crystallography. It crystallizes in the monoclinic, space group P21/ c, with lattice parameters a=0.63270(9)nm, b=2.4264(2)nm, c=1.2128(1)nm, β=92.7 21(9)°, V=1.8597(3)nm3, Z=4, Dc=1.835Mg·m-3, F(000)=1032, μ=1.591mm-1. The molecule is built up of centro-symmetric dimeric entities, in which the four-m embered Ag2S2 ring is planar and the angle of S(3)-Ag(1)-S(3A) is 107.70(2)°f or symmetry requirements. The silver atoms have slightly distorted tetrahedral c oordination environment, and the sulfur atoms of the ETU group occupy four coord ination sites. The two percholate anions in general position balance the charge. In the solid state, the title compound forms three dimensional network structur es through hydrogen bonds. The intermolecular hydrogen bonds and extensive inter molecular interaction connect the 2+ion and two ClO4-anions to cont ribute to the stability of the structure. CCDC: 208731.
The structure of [Cu2(Hdmg)4] (Hdmg=dimethylglyoxime anion) has been determined by X ray crystallography. It is monoclinic, space group P21/n, with Z=2. The lattice parameters: a=0.71601(14)nm; b=1.7044(3)nm; c=1.0126(4)nm; β =113.89(2)° ; Mr=587.52 (C16H28Cu2N8O8); V=1.1299(5)nm3. The copper atom lies in a distorted square pyramidal environment. The four equatorial donors are four nitrogen atoms from bidentate chelate dimethylglyoxime anion ligands. The oxygen atom from the dimethylglyoxime ligand acts as a bridging atom occupying the apical position of the symmetry related copper atom in the dimer structure. The two dimethylglyoximes bridge two copper atoms to form a six member Cu2O2N2 ring, respectively. The thermal gravity (TG) data indicate that the compound [Cu2(Hdmg)4] undergoes two exothermic reactions with loss of the organic ligand to give residue CuO. CCDC: 208729.
The title compound, [CoCl2(C7H5N2CH2Ph)2], has been synthesized and structurally characterized by elemental analysis, IR, UV-Vis spectra, TG-DSC and X-ray crystallography. The coordination geometry of each Co atom is formed, by two N atoms from two benzyl-benzimidazole ligands and by two Cl anions, is of a tetrahedron. The data of EA, IR and UV-vis spectra are in good agreement with the result of crystal structure determination. The thermal gravimetry (TG) data indicate that there are four decomposition steps with five endothermic peaks. The final product of the thermal decomposition is Co. The electrochemical properties of the complex was also studied in H2O/DMF solvent by cyclic voltammetry(CV). CCDC:211442.
