In the title compound, [Ni(C30H26N4O)2](C6H2N3O7)2·2C3H7NO·0.25CH3CH2OH, the NiII ion is coordinated in a distorted octahedral environment by four N atoms and two O atoms from two tridendate 1,3-bis(1-benzyl-1H-benzimidazol-2-yl)-2-oxapropane ligands. The is stabilized by weak intermolecular C—H⋯O hydrogen bonds and weak π–π stacking interactions [centroid–centroid distance 3.501 (3) Å]. As well as the cation, two anions and two dimethylformamide solvent molecules, the also contains an ethanol solvent molecule with 0.25 occupancy.

Reagents and solvents used were of commercially available quality. To a strred solution of 1,3-bis(1-benzylbenzimidazol-2-yl)-2-oxopropane (183.2 mg, 0.4 mmol) in hot MeOH (10 ml) was added Ni(C6H2N3O7)2 (102.9 mg, 0.2 mmol) in MeOH (5 ml). A green crystalline product formed rapidly. The precipitate was filtered off, washed with methanol and absolute ethanol, and dried in vacuo. The dried precipitate was dissolved in DMF to form a green solution that was allowed to evaporate at room temperature. The green crystals suitable for X-ray diffraction studies were obtained after three weeks (Yield, 64%). Elemental analysis - found: C, 59.30; H, 4.51; N, 14.14; calc. for C78.5H71.5N16O18.25Ni, C, 59.31; H, 4.53; N, 14.10%.
All H atoms were found in difference electron maps and were subsequently refined in a riding-model approximation with C—H distances ranging from 0.95 to 0.99 Å and Uiso(H) = 1.2 Ueq or Uiso(H) = 1.5 Ueq for methyl C atoms. The abundance of solvent which is loosely held in the
is probably the reason for the lower than normal precision of this structure.Data collection: RAPID-AUTO (Rigaku/MSC, 2004); cell

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. |

There is widespread interest in bis(2-benzimidazolyl)alkanes and their derivatives because of their wide-ranging anti-virus activity (Roderick et al., 1972), their importance in selective ion-exchange resins (van Berkel et al., 1995), and the possibility of forming supramolecular aggregates with d10 metal ions in which discrete macrocycles, 1, 2 and 3-D architectures have been generated (Piquet et al. 1995). We have been interested in utilizing benzimidazolyl substituted tripodal ligands with nitrogen cores to construct supramolecules, which could provide hydrogen bond donor NH groups and π–π stacking interactions (Hendriks et al., 1982). In our work, efforts are focused on the tridentate ligand, 1,3-bis(1-benzylbenzimidazol-2-yl)-2-oxopropane, which is similar to the histidine imidazole ligand in its coordination aspects (Wu et al. 2005). Since the two arms of this type of ligand can each rotate freely about an O(apical)-C bond, multicomponent complexes or coordination polymeric networks may be expected to form from the assembly of this ligand with metal ions of low coordination number. Herein, the crystal structure of the title compound is presented. The molecular structure of the cation is shown in Fig. 1. The NiII ion is coordinated in a disotorted octahedral environment inolving four N atoms and two O atoms from two tridendate ligands with the axial sites occupied by two oxygen atoms. The crystal structure is stabilized by weak intermolecular C-H···O hydrogen bonds as well as weak π–π stacking interactions with a centroid to centroid distance of 3.501 (3) Å between two benzimidazole ring systems related by the symmetry operator (1-x,-1/2+y,1/2-z).
