In the title mononuclear nickel(II) complex, [Ni(C 3 H 4 N 2 ) 4 ]-(NO 3 ) 2 , the Ni II atom is four-coordinated in a square-planar geometry by four N atoms from four imidazole ligands. The nitrate anions are linked to the nickel(II) complex cations through intermolecular N-HÁ Á ÁO hydrogen bonds.
The title compound, [Cu 2 (C 5 H 9 O 2 ) 4 (C 5 H 5 N) 2 ], consists of centrosymmetric binuclear cage units with four dimethylpropanoate bridges linking the two Cu centres [CuÁ Á ÁCu = 2.6229 (9) A ˚]. The square-pyramidal Cu coordination is completed by a pyridine N atom at the apical site. Astack
