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 ?-? 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.

1,4-Bis(benzimidazol-2-yl)benzene dimethyl-formamide disolvate.

Project description:The aromatic mol-ecule of the title compound, C(20)H(14)N(4)·2C(3)H(7)NO, occupies a special position on an inversion center. The benzimidazole unit (planar to within 0.008?Å) forms a dihedral angle of 9.1?(2)° with the central benzene ring. The benzimidazole H atom participates in a hydrogen bond with the dimethyl-formamide solvent molecule, thus giving rise to the title 1:2 aggregate. These aggregates are further linked in the crystal structure by aromatic ?-? stacking inter-actions [centroid-centroid distance = 6.356?(2)?Å].
