title: Bis[1,3-bis-(1-benzyl-1H-benzimidazol-2-yl)-2-oxapropane]nickel(II) dipicrate-dimethyl-formamide-ethanol (1/2/0.25).
abstract: In the title compound, [Ni(C(30)H(26)N(4)O)(2)](C(6)H(2)N(3)O(7))(2)·2C(3)H(7)NO·0.25CH(3)CH(2)OH, the Ni(II) ion is coordinated in a distorted octa-hedral 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 inter-molecular C-H⋯O hydrogen bonds and weak π-π stacking inter-actions [centroid-centroid distance 3.501 (3) Å]. As well as the cation, two anions and two dimethyl-formamide solvent mol-ecules, the asymmetric unit also contains an ethanol solvent molecule with 0.25 occupancy.
