【 摘 要 】

The title compound, [Cu2(C13H16N3O3)(C12H6N2O2)(H2O)]ClO4·0.5H2O, consists of a cis-oxamide-bridged binuclear CuII complex cation, a perchlorate anion and half a solvent water molecule. One CuII cation is N,N′,N",O-chelated by an N-[3-(dimethylamino)propyl]-N′-(2-hydroxyphenyl)oxamide trianion in a distorted square-planar geometry, whereas the other CuII cation is O,O′-chelated by the oxamide moiety of the anion and N,N′-chelated by a 1,10-phenanthroline-5,6-dione molecule, and a water molecule further coordinates the second CuII cation, completing a distorted square-pyramidal coordination geometry. In the crystal, classical O—H...O hydrogen bonds, weak C—H...O hydrogen-bonding interactions and π–π stacking interactions link the complex cations, anions and solvent water molecules into a three-dimensional supramolecular architecture. In the crystal, the dimethylaminopropyl unit of the oxamide anion is disordered over two positions with an occupancy ratio of 0.561 (11):0.439 (11); the solvent water molecule is also disordered over two positions, the occupancy ratio being 0.207 (10):0.293 (10).
