Catena-Poly[bis-(?3-2-phenyl-acetato-?(3) O,O':O)bis-(?2-2-phenyl-acetato-?(2) O:O')dicopper(II)(Cu-Cu)].

ABSTRACT: The title polymeric compound, [Cu2(C8H7O2)4] n , was synthesized by the reaction of copper acetate with aqueous phenyl-acetic acid. The unique Cu(II) atom is coordinated by five O atoms from the carboxyl-ate groups of phenyl-acetate ligands, and the strongly distorted octa-hedral coordination environment is completed by a Cu-Cu bond of 2.581?(2)?Å, at whose mid-point is located an inversion centre. The crystal structure consists of infinite polymeric linear chains of Cu(2+) ions, running along [100], linked by bridging phenyl-acetate groups.

Project description:The title complex, [Cu(4)(C(5)H(12)NO)(2)(C(2)H(3)O(2))(6)(C(4)H(8)O)(2)](n), consists of dinuclear [Cu(2)(C(5)H(12)NO)(2)(THF)(2)] (THF is tetra-hydro-furan) and [Cu(2)(CH(3)COO)(4)] units linked through acetate ions, generating parallel one-dimensional polymeric chains propagating in the [10] direction. In the first dinuclear unit, Cu(II) ions related by inversion symmetry are bridged by two 3-(dimethyl-amino)propan-1-olate ligands. Likewise, a pair of inversion-related Cu(II) ions are bridged by four acetate groups. The crystallographically independent Cu centers are linked to one another by a single bridging acetate group, generating an infinite chain. The distorted square-pyramidal coordination of the first metal center is completed with an apical THF mol-ecule, with a long Cu-O bond length of 2.476?(5)?Å. The geometry around the other metal atom is close to octa-hedral, and the Cu?Cu separation in this unit is 2.652?(1)?Å. The distance between the metal centers in the first dinuclear unit is considerably longer [3.068?(1)?Å], suggesting little or no bonding inter-action. The Cu?Cu separation between two acetate-bridged independent Cu centers is 4.860?(2)?Å. The THF mol-ecule has methyl-ene groups disordered over two positions, with occupancies of 0.608?(13) and 0.392?(13).

Tetra-kis(?-acetato-?(2)O:O')-bis-[(3-pyridine-carboxaldehyde-?N')]dicopper(II)(Cu-Cu).

Project description:The binuclear title compound, [Cu(2)(CH(3)CO(2))(4)(C(6)H(5)NO)], is located about a center of inversion. The Cu(II) atoms are connected [Cu-Cu = 2.6134?(5)?Å] and bridged by four acetate ligands. Their distorted octa-hedral coordination geometry is completed by a terminal pyridine N atom of a 3-pyridincarboxaldehyde ligand. In the crystal, the complex mol-ecules are linked by C-H?O hydrogen bonds, forming two-dimensional networks lying parallel to the ab plane. These networks are linked via C-H?O hydrogen bonds involving inversion-related 3-pyridinecarboxaldehyde ligands, forming a three dimensional supra-molecular architecture.

Crystal structure of catena-poly[hemi[1,3-bis-(2,6-diisoprop-ylphenyl)imidazolium] [[μ3-acetato-κ(3) O:O:O'-tri-μ2-acetato-κ(6) O:O'-dicopper(II)(Cu-Cu)]-μ-chlorido] di-chloro-methane sesqui-solvate].

Project description:The title copper(II) complex, {(C27H37N2)[Cu4(CH3COO)8Cl]·3CH2Cl2} n , is a one-dimensional coordination polymer. The asymmetric unit is composed of a copper(II) tetra-acetate paddle-wheel complex, a Cl(-) anion situated on a twofold rotation axis, half a 1,3-bis-(2,6-diisoprop-ylphenyl)imidazolium cation (the whole mol-ecule being generated by twofold rotation symmetry) and one and a half of a di-chloro-methane solvent mol-ecule (one being located about a twofold rotation axis). The central metal-organic framework comprises of a tetra-nuclear copper(II) acetate 'paddle-wheel' complex which arises from the dimerization of the copper(II) tetra-acetate core comprising of three μ2-bidentate acetate and one μ3-tridentate acetate ligands per binuclear paddle-wheel complex. Both Cu(II) atoms of the binuclear component adopt a distorted square-pyramidal coordination geometry (τ = 0.04), with a Cu⋯Cu separation of 2.6016 (2) Å. The apical coordination site of one Cu(II) atom is occupied by an O atom of a neighbouring acetate bridge [Cu-O = 2.200 (2) Å], while that of the second Cu(II) atom is occupied by a bridging chloride ligand [Cu⋯Cl = 2.4364 (4) Å]. The chloride bridge is slightly bent with respect to the Cu⋯Cu inter-nuclear axis [Cu-Cl-Cu = 167.06 (6)°] and the tetra-nuclear units are located about a twofold rotation axis, forming the one-dimensional polymer that propagates along [101]. Charge neutrality is maintained by the inclusion of the 1,3-bis-(2,6-diisoprop-ylphenyl)imidazolium cation within the crystal lattice. In the crystal, the cation and di-chloro-methane solvent mol-ecules are linked to the coordin-ation polymer by various C-H⋯O and C-H⋯Cl hydrogen bonds. There are no other significant inter-molecular inter-actions present.

catena-Poly[[?-bromido-(?-hydroxydi-2-pyridylmethano-lato-?N,O:O,N')dicopper(II)(Cu-Cu)]-di-?-bromido].

Project description:The title complex, [Cu(2)Br(3)(C(11)H(9)N(2)O(2))](n), was one of three isolated by slow evaporation of an acetonitrile reaction mixture of CuBr(2) with di-2-pyridyl ketone (1:1 molar ratio). The title complex contains a 2:1 metal-to-ligand ratio of copper(II) with the hydrated form of the ligand, di-2-pyridylmethane-diol. The two copper centers are bridged by a bromide ion and the alk-oxy O atom, and the Cu-Cu distance is 2.9801?(5)?Å. The dimeric units are further linked by bromide ions, leading to a two-dimensional extended bridged structure. O-H?O hydrogen bonds are present in the crystal structure.

catena-Poly[[bis-(2-hydr-oxy-2-phenyl-acetato-κO,O)zinc(II)]-μ-1,2-di-4-pyridylethane-κN:N'].

Project description:The title compound, [Zn(C(8)H(6)O(3))(2)(C(12)H(12)N(2))](n), consists of [Zn(Hopa)(2)] (H(2)opa = 2-hydr-oxy-2-phenyl-acetic acid or mandelic acid) units bridged by 1,2-di-4-pyridylethane (bpe) ligands, forming a polymeric chain developing parallel to the b axis. The bridging bpe ligand is arranged around a twofold axis passing through the middle of the ethane C-C bond. The geometry around the Zn(II) ion is distorted octa-hedral, constructed by four O atoms from two Hopa(-) ligands and two N atoms from two bridging bpe ligands. O-H⋯O hydrogen bonds link the chains, forming a three-dimensional network.
