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 octahedral 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-HO and N-HO hydrogen bonds link the molecules into a two-dimensional supramolecular network parallel to the bc plane.
