丁二酮肟双核铜配合物的合成、结构和性能表征
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. Thecopper atom lies in a distorted square-pyramidal environment. The four equatorial donors are four nitrogen atomsfrom bidentate chelate dimethylglyoxime anion ligands. The oxygen atom from the dimethylglyoxime ligand acts as abridging atom occupying the apical position of the symmetry-related copper atom in the dimer structure. The twodimethylglyoximes 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 organicligand to give residue CuO. CCDC: 208729.
