trans-Bis(2-benzoyl­benzoato-κO 1)bis­(ethanol-κO)bis­(1H-imidazole-κN 3)nickel(II)

In the title centrosymmetric mononuclear nickel(II) complex, [Ni(C14H9O3)2(C3H4N2)2(CH3CH2OH)2], the central NiII 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...O hydrogen bonds stabilize this arrangement. The mol­ecules are linked into chains running along the b axis by N—H⋯O hydrogen bonds

Bis­(benzimidazole-κN 3)bis(2-benzoyl­benzoato-κO)copper(II)

In the title centrosymmetric mononuclear copper(II) compound, [Cu(C14H9O3)2(C7H6N2)2], the central CuII ion is coordinated by two N atoms from two symmetry-related benzimidazole (bim) ligands and two O atoms from two symmetry-related 2-benzoyl­benzoate (2-byba) ligands in a square-planar geometry. The mol­ecules are linked into chains running along the b axis by N—H⋯O hydrogen bonds and the chains are cross-linked by C—H⋯π inter­actions
