Bis{(E)-2-[(2-chloro-3-pyrid-yl)imino-meth-yl]-6-meth-oxy-phenolato-?N,O}copper(II).

ABSTRACT: In the title mononuclear copper(II) complex, [Cu(C(13)H(10)ClN(2)O(2))(2)], the Cu(II) ion, lying on an inversion center, is four-coordinated in a trans-CuN(2)O(2) square-planar geometry by two phenolate O and two imino N atoms from two symmetry-related N,O-bidentate Schiff base ligands. The shortest Cu?Cu distance is 7.5743?(9)?Å. However, there are weak intra-molecular electrostatic inter-actions between the Cu atom and the Cl atom of the ligand, with a Cu?Cl distance of 3.3845?(9)?Å.

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.

Project description:In the title complex, [Cu(C(12)H(7)BrClN(2)O)(2)], the Cu(II) center is tetra-coordinated by two phenolate O and two azomethine N atoms from two independent bidentate 4-bromo-2-[(2-chloro-3-pyrid-yl)imino-meth-yl]phenolate (L) ligands. In the crystal structure, the Cu(II) atom has a distorted square-planar coordination environment. The inter-planar dihedral angles between the benzene and pyridine rings in the individual ligands are 63.83?(4) and 54.43?(3)°, indicating the pyridine ring to have considerably weaker steric hindrance.

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 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.

Bis{2-[(2-pyrid-yl)imino-meth-yl]phenolato}copper(II).

Project description:In the title compound, [Cu(C(12)H(9)N(2)O)(2)], the Cu(II) atom lies on a crystallographic inversion center and has a nearly square-planar geometry. The Cu(II) center coordinates to the phenolic O and azomethine N atoms of the two symmetry-related 2-[(2-pyrid-yl)imino-meth-yl]phenolate ligands. The pyridyl N atoms do not coordinate to the Cu(II) atom but participate in intra-molecular C-H?N hydrogen bonding. ?-? stacking between the benzene rings and between the pyridyl rings [centroid-centroid distances 3.8142?(5) and 3.8142?(5)?Å, respectively] links the mol-ecules into a chain propagating parallel to [100].

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{(E)-4-chloro-2-[(2-chloro-3-pyrid-yl)imino-methyl-?N]phenolato-?O}copper(II).

Project description:In the title complex, [Cu(C(12)H(7)Cl(2)N(2)O)(2)], the Cu(II) center is tetra-coordinated by two phenolic O and two azomethine N atoms from two bidentate 4-chloro-2-[(2-chloro-3-pyrid-yl)imino-meth-yl]phenolate (L) ligands.

The packing of the mol-ecule is controlled by C-H??(Ph) inter-actions and short O?Cl inter-actions [3.196?(4)?Å], linking the mol-ecules into a chain-like structure along the c axis.
