چکیده
In the title compound, [Cu(C(12)H(11)N(2)O(4))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Cu(II) atom lies on a center of inversion and is coordinated by carboxyl-ate O atoms, pyridine N atoms and two water mol-ecules in an elongated octa-hedral geometry. The pyridine ring is oriented at a dihedral angle of 74.83 (12)° with respect to the benzene ring. Intra-molecular O-H⋯O and N-H⋯O hydrogen bonding is observed. The water mol-ecule is a hydrogen-bond donor to the carbonyl O atom of an adjacent carboxyl-ate group, generating a chain running along the a axis. One of the ethyl groups is disordered over two sets of sites in a 0.787 (5):0.213 ratio.

The Cu(II) atom in the title compound, [Cu(C(12)H(11)N(2)O(4))(2)(C(10)H(14)N(2)O)(H(2)O)](n), lies in a square plane defined by the O atoms of the carboxyl-ate ions, the N atom of the N-heterocycle and the water mol-ecule. Coordination by an amido O atom of an adjacent N-heterocycle in the apical direction leads to a polymeric chain running along [01[Formula: see text]]. The chain motif is con...

In the title compound, [Cu(C21H19N6O2)Cl], the Cu(II) atom is in a slightly distorted square-planar coordination involving two O atoms from the pyrazolone rings [Cu-O = 2.088 (10) and 1.975 (10) Å], an N atom of the azo group [Cu-N = 2.048 (13) Å] and a chloride anion [Cu-Cl = 2.183 (5) Å]. The organic anions act as tridentate chelating ligands. The mol-ecules stack in columns along the c axis.

The title compound, [Co(C(7)H(5)O(2))(2)(C(12)H(16)N(3)O(2))(2)(H(2)O)(2)], was obtained from a conventional solvent evaporation method. The complex mol-ecule is centrosymmetric, so pairs of equivalent ligands lie trans to each other in a slightly distorted octa-hedral CoN(2)O(4) geometry. The Co(II) ion is coordinated by the pyridine N atoms from NITpPy ligands [NITpPy is 4,4,5,5-tetra-methyl-...

In the title compound, [Co(C(12)H(9)O(2))(2)(C(4)H(6)N(2))(2)(H(2)O)(2)], the Co(II) ion is located on an inversion centre and displays a distorted octa-hedral coordination geometry. Two O atoms from two water mol-ecules and two carboxyl-ate O atoms from two 2-(naphthalen-1-yl)acetate ligands are in the equatorial plane and two N atoms from two 1-methyl-1H-imidazole ligands are in the axial pos...

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...
