Di-μ-chlorido-bis-(chlorido{2-[(4-ethyl-phen-yl)imino-meth-yl]pyridine-κN,N'}copper(II)).

ABSTRACT: The binuclear title complex, [Cu(2)Cl(4)(C(14)H(14)N(2))(2)], is located on a crystallographic inversion centre. The Cu(II) ion is in a distorted square-pyramid coordination environment formed by the bichelating N-heterocyclic ligand, two bridging Cl atoms and one terminal Cl atom. One of the bridging Cu-Cl bonds is significantly longer than the other.

Di-μ-chlorido-bis-{chlorido[2-(2-furyl-methyl-imino-meth-yl)pyridine-κN,N']nickel(II)}.

Project description:The title dinuclear nickel(II) complex, [Ni(2)Cl(4)(C(11)H(10)N(2)O)(2)], lies on a centre of symmetry located at the centroid of the four-membered ring formed by the two Ni atoms and the bridging chloride ions. The Ni(II) atom is five-coordinated in a square-pyramidal geometry by the imine and pyridine N atoms of the Schiff base ligand, and by one terminal and two bridging Cl atoms. The Ni⋯Ni distance is 3.506 (2) Å. The O atom of the furan substituent in the ligand unit is not involved in coordination to the Ni atom.

A second monoclinic polymorph of di-μ-chlorido-bis-(chlorido{2-[(4-ethyl-phen-yl)imino-meth-yl]pyridine-κ²N,N'}copper(II)).

Project description:The title compound, [Cu₂Cl₄(C₁₄H₁₄N₂)₂], is a new polymorph of a previously reported compound [Dehghanpour et al. (2011 ▶). Acta Cryst. E67, m1296]. The current polymorph was obtained from an acetonitrile solution of the title compound. Like the first polymorph, it is monoclinic (space group P2₁/c). The unique Cu(II) ion in the title centrosymmetric dinuclear complex is in a distorted trigonal-bipyramidal coordination environment formed by the bis--chelating N-heterocyclic ligand, two bridging Cl ligands and one terminal Cl ligand. In the crystal, weak C-H⋯Cl hydrogen bonds are observed in addition to π-π stacking inter-actions, with a centroid-centroid distance of 3.6597 (18) Å.

Project description:The structure of the title compound, [Cd(3)Cl(6)(C(15)H(15)NO(2))(2)(CH(4)O)(2)](n), is based on a layered zigzag polymeric chain along the c axis. The Cd(II) ions are linked by double chlorine bridges alternating between one CdCl(4)(CH(3)OH)(2) and two CdCl(4)(C(15)H(15)NO(2)) octa-hedral coordination units. Additional intrachain N-H⋯O and O-H⋯Cl hydrogen-bond interactions stabilize this arrangement.

Project description:The centrosymmetric title compound, [Pd(2)Cl(2)(C(27)H(26)N)(2)], was obtained by a C-H bond-activation reaction of a Schiff base ligand with Li(2)PdCl(4) in methanol, and was crystallized from dichloro-methane as orange crystals. The Pd atom displays a slightly distorted square-planar geometry, with the N- and C-atom donors in a cis arrangement.

Project description:In the title compound, [ZnBr(2)(C(12)H(9)N(3)O(2))], the Zn(II) ion is bonded to two Br ions and two N atoms of the diimine ligand in a distorted tetra-hedral geometry.

Dichlorido{2-[(4-iodo-phen-yl)imino-meth-yl]pyridine-κN,N'}copper(II).

Project description:The Cu(II) atom in the title complex, [CuCl(2)(C(12)H(9)IN(2))], has a square-planar coordination being N,N'-chelated by the Schiff base ligand, and by two Cl atoms. The geometry is distorted towards square pyramidal owing to a long Cu⋯Cl inter-action of 2.941 (1) Å. This results in the formation of a zigzag chain structure propagating in the c-axis direction.

Dichlorido{2-[(3,4-dimethyl-phen-yl)imino-meth-yl]pyridine-κN,N'}copper(II).

Project description:In the title complex, [CuCl(2)(C(14)H(14)N(2))], the Cu(II) atom exhibits a very distorted tetra-hedral coordination geometry involving two chloride ions and two N-atom donors from the Schiff base ligand.

The chelate ring including the Cu(II) atom is approximately planar, with a maximum deviation of 0.039 (4) Å for one of the C atoms; this plane forms a dihedral angle of 46.69 (9)° with the CuCl(2) plane.
