trans-Bis(2-benzoylbenzoato-kappa O-1)bis(ethanol-kappa O)bis(1H-imidazole-kappa N-3)nickel(II)

Abstract

In the title centrosymmetric mononuclear nickel(II) complex, [Ni(C14H9O3)(2)(C3H4N2)(2)(CH3CH2OH)(2)], the central Ni-II ion lies on an inversion centre and is octahedrally coordinated. The equatorial plane is formed by two O atoms from two symmetry-related 2-benzoylbenzoate ligands and two N atoms from two symmetry-related imidazole ligands, whereas the axial positions are occupied by two O atoms from two ethanol ligands. Intramolecular O-H center dot center dot center dot O hydrogen bonds stabilize this arrangement. The molecules are linked into chains running along the b axis by N-H center dot center dot center dot O hydrogen bonds.
