LETHYL)-1,2-ETHANEDIAMINE](NITRATO-O,O')NICKEL(II) NITRATE

The structure of the title compound, [Ni(C20H24N6)(NO3)](NO3), consist s of a distorted octahedral nickel complex with the central Ni atom co ordinated to two N atoms of the benzimidazole moieties, two ethylenedi amine N atoms and two O atoms of one of the nitrate ions; the other ni trate ion lies in a well defined position in the lattice and plays an important role in crystal packing. The dihedral angle between the two benzimidazole rings is 85.1(1)degrees. The crystal structure is stabil ized by a three-dimensional network of N-H ... O and C-H ... O interac tions, and N-H ... O intermolecular hydrogen bonds.
