Abstract: The title compound, [Ni(C₈H₉N₃)₂(C₈H₈N₃)][N(CN)₂]·H₂O, has been prepared and characterized by X-ray crystallographic analysis. The coordination environment of the nickel(II) ion is a distorted octahedron, with six N donors from two 2-aminomethylbenzimidazole (Hambi) and one ambi^- anion. The Ni-N bond distances range from 2.074 (3) to 2.152 (3) Å, and the primary amine N atoms of ambi possess longer Ni-N bond distances compared with the Ni-N(aromatic amine) bond distances. The three ambi ligands are arranged around the nickel ion in a facial fashion. The dicyanamide counter-anion was found to form extensive hydrogen bonds with both the cations and the water of crystallization.
