title: catena-Poly[[dinitratocopper(II)]-μ-4,4''-bis-(1H-benzimidazol-1-yl)-1,1':4',1''-terphen-yl].
abstract: In the title one-dimensional coordination polymer, [Cu(NO(3))(2)(C(32)H(22)N(4))](n), the Cu(2+) ion (site symmetry 2) is coordinated by two nitrate O atoms and two N atoms from two 4,4'-bis-(benzoimidazol-1-yl)terphenyl (L) ligands in a distorted cis-CuN(2)O(2) square-planar coordination geometry. An alternative description of the metal coordination geometry, if long Cu-O contacts to the bonded nitrate anions are considered, is an extremely distorted cis-CuN(2)O(4) octa-hedron. The complete L ligand is generated by crystallographic twofold symmetry and connects the metal ions into infinite chains propagating in [10[Formula: see text]]. The dihedral angle between the benzimidazole ring system and the adjacent benzene (B) ring is 51.12 (11)° and the dihedral angle between the B ring and the central ring is 19.45 (13)°.
