چکیده
In the title compound, [Ni(NO(3))(C(13)H(20)N(4))(2)]NO(3), the Ni(II) ion shows a distorted octa-hedral geometry formed by four N atoms from two bis-(2-ethyl-5-methyl-1H-imidazol-4-yl)methane ligands and two O atoms from a chelating nitrate anion. Three ethyl groups in the complex cation and the O atoms of the uncoordinated nitrate anion are disordered over two sets of positions [occupancy ratios of 0.52 (3):0.48 (3) and 0.63 (3):0.37 (3), respectively]. In the crystal, inter-molecular N-H⋯O hydrogen bonds connect the complex cations into a zigzag chain along [010] and further N-H⋯O hydrogen bonds between the chains and the uncoordinated nitrate anions lead to layers parallel to (100).

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...
