Tris(2,2′-bi-1H-imidazole-κ(2) N (3),N (3′))­nickel(II) dinitrate N,N-dimethyl­formamide monosolvate

The reaction of nickel salts and 4,4′-bipyridine with 2,2′-bi­imidazole (H(2)biim) yielded the title complex, [Ni(C(6)H(6)N(4))(3)](NO(3))(2)·C(3)H(7)NO. The Ni(II) atom is chelated by three H(2)biim ligands in a distorted octa­hedral coordination geometry. The two nitrate anions and one dimethyl­fo...

Sumario:The reaction of nickel salts and 4,4′-bipyridine with 2,2′-bi­imidazole (H(2)biim) yielded the title complex, [Ni(C(6)H(6)N(4))(3)](NO(3))(2)·C(3)H(7)NO. The Ni(II) atom is chelated by three H(2)biim ligands in a distorted octa­hedral coordination geometry. The two nitrate anions and one dimethyl­formamide (DMF) mol­ecule are not coordinated. The compound has a three-dimensional structure, formed by extensive hydrogen bonding between [Ni(H(2)biim)(3)](2+) cations and nitrate anions, each nitrate anion forming hydrogen bonds with an R (1) (2)(4) motif. The DMF molecule is disordered over three sets of sites, with occupancy ratios of 0.341 (16):0.350 (17):0.309 (19).
