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.

Experimental. The complex was characterized by IR spectral analysis. There is a peak of middle intensity at 3563 cm-1 attributable to the H—O stretching vibration, showing that O—H bond exists in the complex. Three strong peaks at 2239, 2203 and 2141 cm-1 are observed which can be assigned to the stretching vibration of the CN triple bond of dicyanamide. The microelemental analysis results (C 53.40, H 4.77, N 28.69%), agree with the formula [Ni(ambi)3][N(CN)2]OH very well (calculated results: C 53.54, H 4.84, N 28.82%). Consequently, another possibility, i.e. [Ni(ambi)3][N(CN)2]Cl (calculated values: C 51.90, H 4.52, N 27.90%), was dismissed.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
