Tetra-kis(1H-imidazole-κN)(2-phenyl-propanedioato-κO,O)nickel(II).

In the title complex, [Ni(C(9)H(6)O(4))(C(3)H(4)N(2))(4)], the Ni(II) ion is O,O'-chelated by the phenyl-malonato ligand and coordinated by four imidazole ligands in a slightly distorted octa-hedral geometry. In the crystal structure, symmetry-related mol-ecules are linked by N-H⋯O hydrogen bonds, generating a three-dimensional network.
