trans-Bis(2-Benzoylbenzoato-κO-1)bis(Ethanol-κO)bis(1H-Imidazole-κN-3)Nickel(II)

Abstract

In the title centrosymmetric mononuclear nickel(II) complex, [Ni(C <inf>14</inf>H<inf>9</inf>O<inf>3</inf>)<inf>2</inf>(C<inf>3</inf>H <inf>4</inf>N<inf>2</inf>)<inf>2</inf>(CH<inf>3</inf>CH<inf>2</inf>OH) <inf>2</inf>], the central NiII ion lies on an inversion centre and is octa-hedrally coordinated. The equatorial plane is formed by two O atoms from two symmetry-related 2-benzoyl-benzoate 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 mol-ecules are linked into chains running along the b axis by N - H⋯O hydrogen bonds. © 2009 Heren et al.
