چکیده
In the title salt, [Cu(NO(3))(C(7)H(6)N(2))(4)]NO(3), one nitrate anion is coordinated to the Cu(II) atom, which is also coordinated by the N atoms of four N-heterocycles. The geometry at the metal atom is a square pyramid in which the O atom of the anion occupies the apical position [Cu-O = 2.468 (5) and 2.590 (7) Å in the two independent formula units]. The cation lies on a twofold rotation axis; the coordinated nitrate anion is also disordered about this symmetry element. The lattice anion is also disordered about a twofold rotation axis. In the crystal, the cations are linked to the coordinated and free anions by N-H⋯O hydrogen bonds.

The title complex mol-ecule, [Cu(NO(3))(2)(C(4)H(6)N(2))(2)(H(2)O)], has crystallographically imposed twofold symmetry. The Cu(II) atom displays a distorted square-pyramidal CuN(2)O(3) coordination geometry. In the crystal, inter-molecular O-H⋯O hydrogen bonds between the coordinated water mol-ecule and the nitrate anions form chains parallel to the c axis.

In the title compound, [Cu(NO(3))(2)(C(8)H(9)N(3))(2)], the Cu(II) atom, lying on an inversion center, has a distorted octa-hedral coordination environment defined by four N atoms from two chelating 2-amino-methyl-1H-benzimidazole ligands and two O atoms from two monodentate nitrate anions. In the crystal, N-H⋯O hydrogen bonds link the complex mol-ecules into a three-dimensional network. An int...

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...
