Abstract: Green single crystals of the title compound, [Ni(N3)2(C6H6N4)2], were obtained by reacting nickel(II) perchlorate with 2,2'-biimidazole (H2bim) and sodium azide. The azide and H2bim ligands are bonded to the Ni atom, which lies on an inversion centre, with approximately octahedral geometry. The azide anions are terminally bonded in two trans postitions. A two-dimensional supramolecular network is formed through hydrogen bonds between ligand H2bim and azide N atoms.
