title: [mu-N,N'-Bis(2-aminoethyl)oxamidato(2-)]bis[(4,5-diazafluoren-9-one)perchloratocopper(II)] 4,5-diazafluoren-9-one disolvate.
abstract: The title compound, [Cu2(C6)H12N4O2)(ClO4)2(C11H6N2O)2].-2C11H6N2O, contains a dinuclear copper(II) complex which lies about a twofold axis at the mid-point of the C-C bond of the oxamide ligand that bridges the two Cu(II) atoms. The Cu...Cu distance is 5.215 (2) A and the Cu atoms have distorted octahedral coordination geometry. Intramolecular N-H...O and N-H...N hydrogen bonds and intermolecular C-H...O hydrogen bonds, together with pi-pi stacking interactions, dominate throughout the crystal structure.
