Di-?-chlorido-bis-{[2-(8-quinol-yloxy)-acetato-?N,O,O]copper(II)}.

ABSTRACT: The title compound, [Cu(2)(C(11)H(8)NO(3))(2)Cl(2)], is a bicopper(II) complex. Each Cu(II) ion is five-coordinated by two O atoms and one N atom from the (8-quinol-yloxy)acetate ligand, and by two ?(2)-chloride ligands, thus exhibiting a distorted square-pyramidal CuCl(2)NO(2) coordination environment. Each (8-quinol-yloxy)acetate anion acts as a tridentate chelating ligand. In the crystal structure, adjacent quinolyl rings are involved in strong ?-? stacking inter-actions, with inter-planar distances of 3.549?(5) and 3.763?(5)?Å, thereby forming a two-dimensional planar network perpendicular to the ab plane. Furthermore, a weak inter-action [2.750?(4)?Å] is observed within these planes between one Cu(II) ion and a carboxyl-ate O atom from a ligand in an adjacent mol-ecule, which also contributes to the stability of the structure.

Di-?-chlorido-bis-[(1,10-phenanthroline-?N,N')(trichloro-acetato-?O)copper(II)].

Project description:The title compound, [Cu(2)(C(2)Cl(3)O(2))(2)Cl(2)(C(12)H(8)N(2))(2)], features a centrosymmetric binuclear complex. The coordination geometry around the Cu(II) atom is square-pyramidal, comprising two N atoms from a symmetrically chelating 1,10-phenanthroline ligand, one O atom from a trichloro-acetate ligand and two Cl(-) anions. In addition, there is a weak intra-molecular Cu?O inter-action of 2.9403?(14)?Å involving the carbonyl O atom of the trichloro-acetate ligand. The central Cu(2)Cl(2) core takes the form of a rhombus, owing to the disparate Cu-Cl bond lengths. Mol-ecules are connected in the crystal structure by C-H?Cl and C-H?O inter-actions.

Di-?-acetato-bis-[(acetato-?O,O')bis-(iso-nicotinamide-?N)copper(II)].

Project description:The title centrosymmetric bimetallic complex, [Cu(2)(C(2)H(3)O(2))(4)(C(6)H(6)N(2)O)(4)], is composed of two copper(II) cations, four acetate anions and four isonicotinamide (INA) ligands. The asymmetric unit contains one copper cation to which two acetate units bind asymmetrically; one of the Cu-O distances is rather long [2.740?(2)?Å], almost at the limit of coordination. These Cu-O bonds define an equatorial plane to which the Cu-N bonds to the INA ligands are almost perpendicular, the Cu-N vectors subtending angles of 2.4?(1) and 2.3?(1)° to the normal to the plane. The metal coordination geometry can be described as a slightly distorted trigonal bipyramid if the extremely weak Cu-O bond is disregarded, or as a highly distorted square bipyramid if it is not. The double acetate bridge between the copper ions is not coplanar with the CuO(4) equatorial planes, the dihedral angle between the (O-C-O)(2) and O-Cu-O groups being 34.3?(1)°, resulting in a sofa-like conformation for the 8-member bridging loop. In the crystal, N-H?O hydrogen bonds occur, some of which generate a head-to tail-linkage between INA units, giving raise to chains along [101]; the remaining ones make inter-chain contacts, defining a three-dimensional network. There are in addition a number of C-H?O bonds involving aromatic H atoms. Probably due to steric hindrance, the aromatic rings are not involved in significant ??? inter-actions.

Acetato-chlorido[2,2'-(ethane-1,2-di-yl)di-1H-benzimidazole]-copper(II) monohydrate.

Project description:In the title complex, [Cu(CH(3)COO)Cl(C(16)H(14)N(4))]·H(2)O, the Cu(II) ion is five-coordinated by two N atoms from a 2,2'-(ethane-1,2-di-yl)di-1H-benzimidazole ligand, two O atoms from a chelating acetate ligand and one terminal monodentate Cl atom in a distorted square-pyramidal geometry. In the crystal, adjacent mol-ecules are linked through O-H?Cl, N-H?Cl, N-H?O and O-H?O hydrogen bonds into a three-dimensional network.

Di-?-chlorido-bis-[chlorido(1,4,6-trimethyl-6-nitro-1,4-diazepine)copper(II)].

Project description:The title neutral copper complex, [Cu(2)Cl(4)(C(8)H(17)N(3)O(2))(2)], shows a binuclear center with a Cu-(?-Cl)(2)-Cu core, in which each copper ion is coordinated by the N,N,O donor atoms of the tridentate ligand 1,4,6-trimethyl-6-nitro-1,4-diazepine (meaaz-NO(2)) and three chloride exogenous ligands. Each metal ion is facially coordinated by meaaz-NO(2) through N,N,O donor atoms, whereas two bridging and one terminal chloride ions occupy the other face of the highly Jahn-Teller-distorted octa-hedron. Two N atoms from tertiary amine groups of the meaaz-NO(2) ligand and two exogenous Cl atoms with short Cu-N and Cu-Cl distances define the equatorial plane. The coordination around each Cu(II) ion is completed by another Cl atom and an O atom from the NO(2) group, in the axial positions. The binuclear complex exhibits a centrosymmetric structure with point symmetry .

Crystal structure of di-chlorido-bis-(methyl isonicotinate-κN)copper(II).

Project description:In the title compound, [CuCl2(C7H7NO2)2], the square-planar-coordinated Cu(II) ion lies on a centre of symmetry and is bonded to two monodentate methyl-isonicotinate ligands through their N atoms and by two chloride ligands. The mol-ecules pack in a herringbone pattern. Perpendicular to [100] there are weak inter-molecular C-H⋯Cl and C-H⋯O contacts. Along [100] there are infinite chains of edge-sharing octa-hedra linked through the chlorido ligands.

Di-?-chlorido-bis-{[2-(2-pyridylmethyl-amino)ethanesulfonato-?N,N',O]copper(II)}.

Project description:In the title compound, [Cu(2)(C(8)H(11)N(2)O(3)S)(2)Cl(2)], the Cu atoms are five-coordinated in a distorted square-pyramidal geometry by three donor atoms of the deprotonated anionic 2-(2-pyridylmethyl-amino)ethanesulfonate (pmt) ligand and two Cl atoms. The Cl atoms bridge two Cu atoms, giving a binuclear structure; the centroid of the Cu(2)Cl(2) ring lies on a crystallographic center of inversion. The complex is stabilized by hydrogen bonds and ?-? stacking inter-actions [average inter-planar distance = 3.4969?(1)?Å and ring-centroid separation distance = 4.1068?(4)?Å].

Di-?-chlorido-bis-[chlorido(dimethoxy-phenyl-phosphine)palladium(II)].

Project description:The title compound, [Pd(2)Cl(4)(C(8)H(11)O(2)P)(2)], is binuclear and disposed about a crystallographic centre of symmetry with a Pd?Pd distance of 3.4662?(17)?Å. It has a similar geometry to that observed in the triphenyl-phosphite and triphenyl-phosphine analogues. The Pd-P bond length is ca 0.04?Å shorter than those in mononuclear PdCl(2)(P(OMe)(2)Ph)(2), possibly due to the lower trans-influence of the bridging Cl(-) compared to a single-bonded Cl(-) atom.

Tetra-imidazole-bis(trichloro-acetato)copper(II).

Project description:The title compound, [Cu(C(2)Cl(3)O(2))(2)(C(3)H(4)N(2))(4)], was prepared by the reaction of imidazole and trichloro-acetatocopper(II). The Cu(II) atom adopts a distorted octa-hedral coordination geometry, binding the N atoms of four imidazole ligands and the carboxyl-ate O atoms of two trichloro-acetate anions. The mol-ecular structure and packing are stabilized by N-H?O hydrogen-bonding inter-actions. Close inter-molecular Cl?Cl contacts [3.498?(3)?Å] are also found in the structure.

Di-?-chlorido-bis-{aqua-chlorido[2,2'-thio-bis(pyridine N-oxide)-?O]copper(II)}.

Project description:The crystal structure of the title compound, [Cu(2)Cl(4)(C(10)H(8)N(2)O(2)S)(2)(H(2)O)(2)], comprises neutral centrosymmetric ?-chloride-bridged dinuclear units. Each Cu(II) ion is penta-coordinated by three chloride ligands, a pyridine N-oxide O atom and a water mol-ecule. Intra- and inter-molecular O-H?O hydrogen bonds occur between the coordinated water mol-ecules and the uncoordinated and coordinated pyridine N-oxide groups of the 2,2'-thio-bis(pyridine N-oxide) ligands, respectively.

Di-μ-chlorido-bis-(chlorido{2,2'-[3-(1H-imidazol-4-ylmeth-yl)-3-aza-pentane-1,5-di-yl]diphthalimide}copper(II)).

Project description:The centrosymmetric dinuclear Cu(II) complex, [Cu(2)Cl(4)(C(24)H(21)N(5)O(4))(2)], was synthesized by the reaction of CuCl(2)·2H(2)O with the tripodal ligand 2,2'-[3-(1H-imid-azol-4-ylmeth-yl)-3-aza-pentane-1,5-di-yl]diphthalimide (L). Each of the Cu(II) ions is coordinated by two N atoms from the ligand, two bridging Cl atoms and one terminal Cl atom. The Cu(II) coordination can be best be described as a transition state between four- and five-coordination, since one of the bridging Cl atoms has a much longer Cu-Cl bond distance [2.7069 (13) Å] than the other [2.2630 (12) Å]. In addition, the Cu⋯Cu distance is 3.622 (1) Å. The three-dimensional structrure is generated by N-H⋯O, C-H⋯O and C-H⋯Cl hydrogen bonds and π-π inter-actions [centroid-centroid distances = 3.658 (4) and 4.020 (4) Å].
