Abstract: In the title compound, [Ni(C₃₀H₂₆N₄O)₂](C₆H₂N₃O₇)₂·2C₃H₇NO·0.25CH₃CH₂OH, the Ni^II 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 crystal structure is stabilized by weak intermolecular C-HO hydrogen bonds and weak - stacking interactions [centroid-centroid distance 3.501 (3) Å]. As well as the cation, two anions and two dimethylformamide solvent molecules, the asymmetric unit also contains an ethanol solvent molecule with 0.25 occupancy.
