title: Bis[2,6-bis-(1H-benzimidazol-2-yl)pyridine]-nickel(II) dipicrate dimethyl-formamide disolvate.
abstract: In the title compound, [Ni(C(19)H(13)N(5))(2)](C(6)H(2)N(3)O(7))(2)·2C(3)H(7)NO, the Ni(II) ion is coordinated by two tridentate 2,6-bis-(1H-benzimidazol-2-yl)pyridine ligands in a distorted octa-hedral geometry. In the crystal structure, the picrate anions and solvent dimethyl-formamide (DMF) mol-ecules are connected to the cation via inter-molecular N-H⋯O hydrogen bonds. Further stabilization is provided by weak inter-molecular C-H⋯O hydrogen bonds. One of the DMF moleclues is disordered over two sites with refined occupancies of 0.737 (3) and 0.263 (3).
