| Abstract: The structure of [Cu2(Hdmg)4] (Hdmg=dimethylglyoxime anion) has been determined by X-ray crystallog-raphy. 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. |
