Abstract

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 crystal structure 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 asymmetric unit also contains an ethanol solvent molecule with 0.25 occupancy.
