✦ Synopsis

The title complex, [Cu(NO 3 ) 2 (C 3 H 6 N 2 O 2 ) 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) A ˚] from two chelating malonamide ligands and two terminal NO 3 groups in a distorted octahedral geometry. The crystal packing is stabilized by intermolecular N-HÁ Á ÁO hydrogen bonds.

In the title complex, [Cu(C~8~H~6~NO~2~)~2~(C~6~H~7~NO)~2~(H~2~O)], the Cu^2+^ ion has a highly distorted square-bipyramidal (4 + 1 + 1) coordination environment, and is bonded to three carboxylate O atoms of two 3-pyridylacrylate anions (monodentate and asymetric bidentate), two pyridine N atoms of
