Abstract:
In the title compound, [Ni(C9H7N2O2)2(C2H5OH)2], the Ni(II) ion is situated on an inversion center and is coordinated by two N and two O atoms from two 2-(1H-benzimidazol-2-yl)acetate (L) ligands and by two O atoms from two ethanol ligands in a distorted octa-hedral geometry. In the L ligand, the acetate group deviates significantly from the benzimidazole plane, the C-C-C-O(coordinating) torsion angle being 34.2 (5)°. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into a two-dimensional supra-molecular network parallel to the bc plane.
