✦ Synopsis
The asymmetric unit of the title compound, [Cu(C~12~H~9~O~2~)~2~], contains one half-molecule; the Cu atom lies on a centre of symmetry. The chelate ring is not planar and has a twist conformation. The dihedral angle between the naphthalene six-membered rings is 3.55 (3)°.

The structure of the title complex, [Ni 2 (C 5 H 7 O 2 ) 4 (H 2 O) 2 ]Á-0.5H 2 O, is dimeric and corresponds to the trimeric structure of bis(acetylacetonato)nickel(II) in which one Ni(acac) 2 unit is replaced by two water molecules. The centrosymmetric molecule comprises two O-O edge-shared octahed
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
