(Azido-κN)[6-meth-oxy-2-(2-pyridylmethyl-imino-meth-yl)phenolato-κN,N',O]copper(II).

ABSTRACT: The title compound, [Cu(C(14)H(13)N(2)O(2))(N(3))], is a monomeric neutral complex with one unsymmetrical 6-meth-oxy-2-(2-pyridylmethyl-imino-meth-yl)phenolate Schiff base ligand and one azide ligand. The mol-ecules are connected by a combination of two π-π inter-actions [centroid-centroid distances 3.359 (3) and 3.378 (2) Å] and one C-H⋯N hydrogen bond into a two-dimensional supra-molecular network structure.

Bis[2-meth-oxy-6-(3-pyridylmethyl-imino-meth-yl)phenolato-?N,O]copper(II).

Project description:In the title complex, [Cu(C(14)H(13)N(2)O(2))(2)], the Cu(II) ion is located on a crystallographic inversion center. The complex thus adopts a square-planar trans-[CuN(2)O(2)] coordination geometry, with the Cu(II) ion coordinated by two 2-meth-oxy-6-(3-pyridylmethyl-imino-meth-yl)phenolate (Schiff base) ligands. The aryl and pyridyl rings in the Schiff base are almost perpendicular to each other, with a dihedral angle of 87.61?(6)° between the planes of the two six-membered rings. The pyridyl ring was refined using a disorder model with approximately 70% occupancy for the major component.

Bis{2-meth-oxy-6-[(3-methoxy-prop-yl)imino-meth-yl]phenolato-κN,O}copper(II).

Project description:The title complex, [Cu(C(12)H(16)NO(3))(2)], adopts a distorted square-planar coordination geometry with the Cu(II) ion situated on a crystallographic inversion center. The two Schiff base ligands are coordinated in a trans fashion. In the crystal structure, non-classical inter-molecular C-H⋯O hydrogen bonds involving the ether O atoms link the Schiff base mol-ecules into a two-dimensional network parallel to (101).

Bis{?-2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}bis-({2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}copper(II)).

Project description:The title compound, [Cu2(C9H10NO2)4], is built of discrete centrosymmetric dimers. The Cu(II) atoms are each five coordinated by two deprotonated Schiff base ligands that are bonded differently to the metal atoms. Of the two phenolate O atoms, one is coordinated to one Cu(II) atom, whereas another bridges the two metal atoms. The basal plane of the square pyramid around Cu(II) atoms is formed by the imino N and phenolate O atoms of the bidentate and the monodentate/bidentate Schiff base ligands. The bridging phenolate oxygen occupies the apical position of the coordination sphere with a considerably longer Cu-O bond length. In the crystal, the dimeric mol-ecules pack relative to each other in such a way that the Cu2O2 planes of adjacent dimers are orthogonal.

(Dimethyl-formamide-?O)[2-meth-oxy-6-(2-pyridylmethyl-imino-meth-yl)phenolato-?N,N',O](thio-cyanato-?N)copper(II).

Project description:In the title compound, [Cu(C(14)H(13)N(2)O(2))(NCS)(C(3)H(7)NO)], the Cu(2+) ion is coordinated by an N,N',O-tridentate 2-meth-oxy-6-(2-pyridylmethyl-imino-meth-yl)phenolate ligand, an N-bonded thio-cyanate ion and an O-bonded dimethyl-formamide (DMF) mol-ecule, resulting in a distorted CuN(3)O(2) square-based pyramidal geometry for the metal ion, with the DMF O atom in the apical site. The dihedral angle between the aromatic rings in the ligand is 8.70?(16)°. The S atom is disordered over two positions in a 0.901?(6):0.099?(6) ratio. In the crystal, mol-ecules inter-act by way of ?-? stacking inter-actions [centroid-centroid separation = 3.720?(2)?Å].

Bis[2-(cyclo-pentyl-imino-meth-yl)-5-meth-oxy-phenolato]copper(II).

Project description:The title compound, [Cu(C(13)H(16)NO(2))(2)], is a mononuclear copper(II) complex derived from the Schiff base ligand 2-(cyclo-pentyl-imino-meth-yl)-5-meth-oxy-phenol and copper acetate. The Cu(II) atom is four-coordinated by the phenolate O atoms and imine N atoms from two Schiff base ligands, in a highly distorted square-planar geometry. The O- and N-donor atoms are mutually trans and the dihedral angle between the two benzene rings is 55.8?(3)°.

Project description:In the mononuclear title complex, [Cu(C(14)H(13)N(2)O(2))(2)], the Cu(II) atom lies on an inversion centre and adopts a square-planar coordination geometry. The dihedral angle formed by the pyridine and benzene rings is 74.61?(5)°. Intra-molecular C-H?O hydrogen bonds are present. The crystal structure is stabilized by weak aromatic ?-? stacking inter-actions involving neighbouring pyridine rings [centroid-centroid distance = 3.853?(2)?Å].

Project description:In the title compound, [Cu(C(12)H(16)NO(5))(2)]·2H(2)O, the Cu(II) ion adopts a trans-CuN(2)O(4) octa-hedral geometry arising from two N,O,O'-tridentate 6-meth-oxy-2-{[tris-(hydroxy-meth-yl)meth-yl]-imino-meth-yl}phenolate ligands. The Jahn-Teller distortion of the copper centre is unusally small. In the crystal structure, O-H?O hydrogen bonds, some of which are bifurcated, link the component species.

Project description:The title compound, [Cu(C(13)H(11)N(2)O)(C(2)N(3))]·H(2)O, is a mononuclear copper(II) complex in which the Cu(II) ion has a slightly distorted square-planar geometry and is coordinated by two N atoms and one O atom from the Schiff base ligand and by an N atom from dicyanamide. The O atoms of water mol-ecules contribute to O-H?N, O-H?O hydrogen bonds, leading to the formation of sheets parallel to the ac plane. There are also weak inter-actions between inversion-related mol-ecules.

Bis{?-2-[1-(2-Pyridylmethyl-imino)eth-yl]phenolato}bis-[azido-copper(II)].

Project description:The title compound, [Cu(2)(C(14)H(13)N(2)O)(2)(N(3))(2)], was synthesized by the reaction of Cu(NO(3))(2)·3H(2)O with the Schiff base 2-[1-(2-pyridylmethyl-imino)eth-yl]phenol (HL) in methanol-water solution, adding NaN(3) as the bridging ligand. The asymmetric unit contains one half-mol-ecule, the other half being generated by the inversion center. Each Cu(II) atom shows a slightly distorted trigonal-pyramidal geometry formed by two N atoms and one O atom from one Schiff base ligand, by another O atom of a second Schiff base ligand and by an azide N atom. The crystal structure is stabilized by intermolecular C-H?N hydrogen bonds.

A one-dimensional double-chain structure is formed along [001] by O?H-O hydrogen bonds and the Ni?O [2.617?(3)?Å] inter-actions.
