Abstract

The title complex, [Cu(NO3)2(C3H6N2O2)2], exists in the crystal structure as a monomer and possesses a crystallographically imposed center of symmetry. The Cu atom is coordinated by six O atoms [Cu—O = 1.9339 (10)–2.3964 (11) Å] from two chelating malonamide ligands and two terminal NO3 groups in a distorted octa­hedral geometry. The crystal packing is stabilized by inter­molecular N—H⋯O hydrogen bonds. [ABSTRACT FROM AUTHOR]

Abstract

The title complex, [CuCl2(C3H6N2O2)2], exists in the crystal structure as a monomer and possesses a crystallographically imposed center of symmetry. The Cu atom is coordinated by two Cl atoms [Cu—Cl = 2.7696 (3) Å] and four O atoms [Cu—O = 1.9484 (8) and 1.9769 (9) Å] from two chelating malonamide ligands in a distorted octa­hedral geometry. In the crystal structure, a three-dimensional hydrogen-bonding network is formed by inter­molecular N—H⋯O and N—H⋯Cl inter­actions. [ABSTRACT FROM AUTHOR]
