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.

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.

Crystal structure of catena-poly[calcium-di-μ3-benzoato-κ(6) O,O':O-μ2-(dimethyl sulfoxide)-κ(2) O:O].

Project description:In the title complex, [Ca(C7H5O2)2(C2H6OS)] n , the Ca(2+) ion (site symmetry m..) is surrounded by eight O atoms, six from two bridging-chelating tridentate benzoate carboxyl groups and two from a bridging dimethyl sulfoxide mol-ecule (point group symmetry m..), giving an irregular coordination geometry [Ca-O bond length range = 2.345 (2)-2.524 (2) Å]. One-dimensional coordination complex chains extending parallel to c are generated in which the triply μ2-O-bridged Ca(2+) cations are separated by 3.6401 (5) Å. In the crystal, weak intra-chain C-H⋯π hydrogen bonds are present between the methyl H atoms of the dimethyl sulfoxide mol-ecules as donors and the aromatic rings as acceptors [C-H⋯Cg = 3.790 (4) Å].

Tetra-kis(μ-acetato-κ(2)O:O')-bis-[(3-pyridine-carboxaldehyde-κN')]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[bis(formato-κO)bis-[μ2-1,1'-(1,4-phenyl-ene)bis-(1H-imidazole)-κ(2) N (3):N (3')]cobalt(II)].

Project description:A red block-shaped crystal of the title compound, [Co(HCOO)2(C12H10N4)2] n , was obtained by the reaction of cobalt(II) nitrate hexa-hydrate, formic acid and 1,1'-(1,4-phenyl-ene)bis-(1H-imidazole) (bib) mol-ecules. The asymmetric unit consists of one Co(II) cation, one formate ligand and two halves of a bib ligand. The central Co(II) cation, located on an inversion centre, is coordinated by two carboxyl-ate O atoms and four N atoms from bib ligands, completing an octa-hedral coordination geometry. The Co(II) centres are bridged by bib ligands, giving a two-dimensional net. Topologically, taking the Co(II) atoms as nodes and the bib ligands as linkers, the two-dimensional structure can be simplified as a typical sql/Shubnikov tetra-gonal plane network. The structure features C-H⋯O hydrogen-bonding inter-actions between formate and bib ligands, resulting in a three-dimensional supra-molecular network.

Crystal structure of bis-(μ2-meth-anolato-κO:κO)hexa-methyl-bis-(μ2-tri-phenyl-acetato-κO:κO')bis-(μ2-tri-phenyl-acetato-κ2 O,O':κO)dialuminiumdi-lanthanum toluene tetra-solvate.

Project description:The title compound, [Al2La2(C20H15O2)4(CH3)6(CH3O)2]·4CH3C6H5 or [{La(Ph3CCOO)2(Me3AlOMe)}2]·4CH3C6H5, was formed in a reaction between lanthanum tris-(tetra-methyl-aluminate) and tri-phenyl-acetic acid (1:1) with unintended partial oxidation. The tri-phenyl-acetate ligand exhibits μ2-κ1 O:κ1 O' bridging and μ2-κ2 O,O':κ1 O semi-bridging coordination modes, forming a dimeric La2(μ-OCO)4 core. The semi-bridging tri-phenyl-acetate group provides additional bonding with an La3+ cation via the π-system of one of its phenyl rings. The tri-methyl-meth-oxy-aluminate anion, which is coordinated to the La3+ cation by its O atom, displays a rather long La-CMe bond. Two toluene mol-ecules are each disordered over two orientations about centres of symmetry with site occupancy factors of 0.5. The title compound represents the first example of an LnIII complex containing both alkyl alkoxide aluminate and π-bounded arene fragments.

catena-Poly[[tetra-kis(μ(2)-acetato-κO:O')dicopper(II)(Cu-Cu)]-μ(2)-acetato-κO:O'-[bis-[μ(2)-3-(dimethyl-amino)propan-1-olato]-κN,O:O;κO:N,O-bis-[(tetra-hydro-furan-κO)copper(II)]]-μ(2)-acetato-κO:O'].

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).

Project description:In the title polymeric coordination compound, [Sn(CH(3))(3)(C(8)H(6)ClO(2))](n), the Sn atoms exhibit a distorted trigonal-bipyramidal geometry with the carboxyl-ate O atoms of the 2-chloro-phenyl-acetato ligands in axial positions and with the equatorial sites occupied by the three methyl groups. Adjacent Sn atoms are bridged by coordination to the two O atoms of each 2-chloro-phenyl-acetato ligand, forming a chain structure.

Project description:The asymmetric unit of the title compound, [Cd(NCS)2(CH3CN)] n , consists of one Cd(II) cation, two thio-cyanate anions and one aceto-nitrile ligand, all in general positions. The Cd(II) cation is coordinated by three N atoms of two thio-cyanate anions and one aceto-nitrile ligand, as well as three S atoms of symmetry-related thio-cyanate anions within a slightly distorted octa-hedral coordination environment. The Cd(II) cations are linked by μ-1,3(N,S) and μ-1,1,3(S,S,N) thio-cyanate anions into layers that are located in the ab plane.
