title: Bis[1,3-bis-(1-benzyl-1H-benzimidazol-2-yl)-2-oxapropane]zinc(II) dipicrate dimethyl-formamide disolvate.
abstract: In the title compound, [Zn(C(30)H(26)N(4)O)(2)](C(6)H(2)N(3)O(7))(2)·2C(3)H(7)NO, the Zn(II) ion is coordinated in a distorted octa-hedral environment involving four equatorial N atoms and two O atoms in axial sites. The dihedral angles between the benzimidazole ring system and the phenyl rings in each of the benzyl-benzimidazole units are 78.56 (12), 81.68 (11), 75.76 (10) and 85.78 (9)°. In the crystal structure, there are weak but significant inter-molecular π-π stacking inter-actions with centroid-centroid distances of 3.685 (1) and 3.978 (1) Å.
