Aqua-(azido)[N-(pyridin-2-ylcarbon-yl)pyridine-2-carboxamido-?(3) N,N',N'']copper(II).

ABSTRACT: The title compound, [Cu(C12H8N3O2)(N3)(H2O)], was formed by the air oxidation of 2-(amino-meth-yl)pyridine in 95% ethanol in the presence of copper(II) nitrate and sodium azide with condensation of the resulting picolinamide mol-ecules to generate the imide moiety. The Cu(II) ion has a square-pyramidal coordination sphere, the basal plane being occupied by four N atoms [two pyridine (py) N atoms, the imide N atom and an azide N atom] in a nearly planar array [mean deviation = 0.048?(6)?Å] with the Cu(II) ion displaced slightly from the plane [0.167?(5)?Å] toward the fifth ligand. The apical position is occupied by a coordinating water mol-ecule [Cu-O = 2.319?(4)?Å]. The crystal structure is stabilized by hydrogen-bonding inter-actions between the water mol-ecules and carbonyl O atoms. The inversion-related square-pyramidal complex molecules pack base-to-base with long Cu?Npy contact distances of 3.537?(9)?Å, preventing coordination of a sixth ligand.

Bis[N-(pyridin-2-ylcarbon-yl)pyridine-2-carboxamidato]iron(III) perchlorate monohydrate.

Project description:The structure of the title salt complex, [Fe(C(12)H(8)N(3)O(2))(2)]ClO(4)·H(2)O, contains one Fe(III) cation, two N-(pyridin-2-ylcarbon-yl)pyridine-2-carboxamidate (bpca(-)) anions, one perchlorate anion and one water mol-ecule. The Fe(III) cation has an approximate octa-hedral geometry, defined by six N atoms from two bpca(-) anions. The nearly parallel [dihedral angle = 1.50?(1)°] bpca(-) anions form two-dimensional supermolecules along the a axis by the way of weak ?-? stacking inteactirons [centroid-centroid distances = 3.948?(2), 4.000?(2), 3.948?(2), 3.911?(2), 3.897?(2), 3.984?(2) and 3.929?(2)?Å]. Intra- and inter-molecular C-H?O hydrogen bonding occurs. The water mol-ecule [occupancies 0.520?(5) and 0.480?(5)], two carbonyl O atoms [occupancies 0.622?(7) and 0.378?(7)] and the four perchlorate O atoms [occupancies 0.887?(4) and 0.113?(4)] are each disordered over two positions.

Di-?-azido-?N:N-bis-{aqua-[bis-(1H-benzimidazol-2-ylmeth-yl)amine]-copper(II)} dinitrate.

Project description:In the centrosymmetric dinuclear title complex, [Cu(2)(N(3))(2)(C(16)H(15)N(5))(2)(H(2)O)(2)](NO(3))(2), the Cu(II) ion is in a distorted octa-hedral coordination environment with long axial Cu-N(azide) [2.821?(6)?Å] and Cu-O(water) [2.747?(5)?Å] bonds as a result of the Jahn-Teller effect. Two symmetry-related azide ligands bridge in ?(2)-modes giving a Cu?Cu distance of 3.533?(2)?Å. In the crystal, N-H?O and O-H?O hydrogen bonds link the components into a three-dimensional network. In addition, there are weak inter-molecular C-H?N hydrogen bonds and ?-? stacking inter-actions with centroid-centroid distances ranging from 3.562?(2) to 3.974?(2)?Å.

catena-Poly[[bis-(acetato-?O)aqua-copper(II)]-?-5-(pyridin-3-yl)pyrimidine-?N:N].

Project description:In the title compound, [Cu(CH(3)CO(2))(2)(C(9)H(7)N(3))(H(2)O)](n), the Cu(II) ion is penta-coordinated in a square-pyramidal geometry. The N atoms of the two chelating symmetry-related 5-(pyridin-3-yl)pyrimidine ligands and the O atoms of the two monodentate acetate anions are nearly coplanar, with a mean deviation from the least-squares plane of 0.157?(2)?Å and the Cu(II) ion is displaced by 0.050?(3)?Å from this plane towards the apical water O atom. Bridging through the bis-monodentate 5-(pyridin-3-yl)pyrimidine ligand forms a one-dimensional coordination polymer extending parallel to [010]. In the crystal, O-H?O hydrogen bonds link the mol-ecules into a two-dimensional supra-molecular structure parallel to (100). The crystal studied was an inversion twin with a 0.57?(3):0.43?(3) domain ratio.

catena-Poly[[[di-aqua-bis-[1,2-bis-(pyridin-4-yl)diazene]copper(II)]-μ-1,2-bis-(pyridin-4-yl)diazene] bis-(perchlorate)].

Project description:In the title compound, {[Cu(C10H8N4)3(H2O)2](ClO4)2} n , the coordination environment of the cationic Cu(II) atom is distorted octa-hedral, formed by pairs of symmetry-equivalent 1,2-bis-(pyridin-4-yl)diazene ligands, bridging 1,2-bis-(pyridin-4-yl)diazene ligands and two non-equivalent water mol-ecules. The 1,2-bis-(pyridin-4-yl)diazene mol-ecules form polymeric chains parallel to [-101] via azo bonds which are situated about inversion centres. Since the Cu(II) atom is situated on a twofold rotation axis, the monomeric unit has point symmetry 2. The perchlorate anions are disordered in a 0.536 (9):0.464 (9) ratio and are acceptors of water H atoms in medium-strong O-H⋯O hydrogen bonds with graph set R 4 (4)(12). The water mol-ecules, which are coordinated to the Cu(II) atom and are hydrogen-bonded to the perchlorate anions, form columns parallel to [010]. A π-π inter-action [centroid-centroid distance = 3.913 (2) Å] occurs between pyridine rings, and weak C-H⋯O inter-actions also occur.

(Azido-?N){(E)-2-[1-(pyridin-2-yl)ethyl-idene-amino]-phenolato-?(3) N,N',O}copper(II).

Project description:In the title complex, [Cu(C13H11N2O)(N3)], the Cu(II) cation is four-coordinated by an N2O donor set of the tridentate Schiff base ligand and by the terminal N atom of the azide anion, forming a slightly distorted square-planar configuration.

[Di-aqua-sesqui(nitrato-κO)hemi(perchlorato-κO)copper(II)]-μ-{bis-[5-methyl-3-(pyridin-2-yl)-1H-pyrazol-4-yl] selenide}-[tri-aqua-(perchlorato-κO)copper(II)] nitrate monohydrate.

Project description:In the binuclear title complex, [Cu2(ClO4)1.5(NO3)1.5(C18H16N6Se)(H2O)5]NO3·H2O, both Cu(II) ions are hexa-coordinated by O and N atoms, thus forming axially elongated CuO4N2 octa-hedra. The equatorial plane of each octa-hedron is formed by one chelating pyrazole-pyridine fragment of the organic ligand and two water mol-ecules. The axial positions in one octa-hedron are occupied by a water mol-ecule and a monodentately coordinated perchlorate anion, while those in the other are occupied by a nitrate anion and a disordered perchlorate/nitrate anion with equal site occupancy. The pyrazole-pyridine units of the organic selenide are trans-oriented to each other with a C-Se-C angle of 96.01 (14)°. In the crystal, uncoordinated nitrate anions and the coordinating water mol-ecules are involved in O-H⋯O and N-H⋯O hydrogen bonds, forming a bridge between the pyrazole group and the coordinating water mol-ecules. Further O-H⋯O hydrogen bonds between the complex mol-ecules and a π-π stacking inter-action with a centroid-centroid distance of 3.834 (4) Å are also observed.

Project description:In the crystal structure of the title complex, [Cu(C(4)H(5)O(2))(2)(C(5)H(5)N)(2)(H(2)O)], the Cu(II) cation is located on a twofold rotation axis and coordinated by two methyl-acrylate anions, two pyridine ligands and one water mol-ecule in a distorted square-pyramidal geometry. The coordinated water mol-ecule is also located on the twofold axis. In the crystal structure O-H⋯O hydrogen bonds link the mol-ecules, forming chains along the c axis.
