A pair of linear cyanamide (NCNH(2)) ligands, two monodentate 4-(1H-imidazol-1-yl)phenol (L) ligands and two nitrate anions link the Cu(II) atom into a mononuclear unit, [Cu(NO(3))(2)(C(9)H(8)N(2)O)(2)(NCNH(2))(2)]. The coordination polyhedron of the Cu atom is an elongated octa-hedron distorted by Jahn-Teller effects. Inter-molecular O-H⋯O, O-H⋯N, N-H⋯O and N-H⋯N hydrogen-bonding inter-actions link these units into a three-dimensional supra-molecular architecture.
