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.
The crystal and molecular structure of [CoCl2(N4 trzCH2CH2COPh)4]·6H2O (trz=1,2,4 triazole) has been determined by X ray diffraction. It crystallizes in the monoclinic system, space group P21/c, with unit cell parameters a=0.8039(2)nm, b=1.0822(2)nm, c=2.9013(6)nm, β=94.79(3)°, and Z=4. Each cobalt atom is coordinated by four N atoms of triazole from four 1 propiophenone 1,2,4 triazole ligands and two chloride anion in cis arrangement with almost perfect octahedral coordination geometry. In addition to the coordinating cobalt complex, there are six uncoordinated water molecules, which complete the crystal structure. In the solid state, the title compound forms three dimensional network structure through hydrogen bonds. The intermolecular hydrogen bonds connect the [CoCl2(C2H2N3CH2CH2COPh)4] and H2O moieties. CCDC: 200711.
