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.
