Catena-Poly[[[aqua-pyridine-zinc(II)]-μ(2)-3,3'-(p-phenyl-ene)diacrylato] pyridine solvate].

ABSTRACT: The title compound, {[Zn(C(12)H(8)O(4))(C(5)H(5)N)(H(2)O)]·C(5)H(5)N}(n), has been prepared by hydro-thermal reaction. The Zn(II) atom is six-coordinated by four carboxyl-ate O atoms of two p-phenylenediacrylate (ppda(2-)) ligands, one N atom of a pyridine mol-ecule and one O atom of a water mol-ecule in a distorted octa-hedral environment. The carboxyl-ate groups of the ppda(2-) anions are in a bridging-chelating mode, in which two O atoms chelate one Zn(2+) ion. These connections result in an extended chain structure. Parallel packing of the chains forms a two-dimensional network with inter-molecular edge-to-face inter-actions. Further linkages between the layers through O-H⋯O hydrogen-bonding inter-actions result in a three-dimensional supra-molecular architecture with one-dimensional recta-nglar channels.

Crystal structure of catena-poly[[di-aqua-cadmium(II)]-μ-3,3'-(1,3-phenyl-ene)diacrylato].

Project description:In the crystal of the title polymeric complex, [Cd(C12H8O4)(H2O)2] n , the Cd(II) cation, located on a twofold rotation axis, is coordinated by two water mol-ecules and chelated by two phenyl-enediacrylate anions (mpda) in a distorted octa-hedral geometry. The mpda anions bridge the Cd(II) cations, forming helical chains propagating along the c-axis direction. The mpba anion has twofold symmetry with two benzene C atoms located on the twofold rotation axis. In the crystal, O-H⋯O hydrogen bonds link the polymeric helical chains into a three-dimensional supra-molecular architecture.

Project description:In the title polymeric coordination complex, {[Cd(C(22)H(20)N(2)O(6))(H(2)O)(4)](NO(3))(2)·0.5H(2)O}(n), obtained from the self-assembly of the flexible double betaine 3,3'-[p-phenyl-enebis(oxymethyl-ene)]bis-(1-pyridinioacetate) with cadmium nitrate, both the octa-hedrally coordinated Cd(II) cation and the substituted betaine ligand lie on inversion centres. The chains constructed through the trans-related acetate groups of the ligand are inter-connected via O-H⋯O hydrogen bonds involving coordinated aqua ligands, the nitrate anions and the partial-occupancy (0.25) water mol-ecule of solvation, forming a three-dimensional structure.

catena-Poly[[[aqua-tripyridine-cobalt(II)]-μ-5-amino-2,4,6-triiodoisophthalato-κO:O] pyridine solvate].

Project description:The reaction of cobalt(II) nitrate with 5-amino-2,4,6-tri-iodo-isophthalic acid (ATPA) in pyridine solution leads to the formation of the title compound, {[Co(C(8)H(2)I(3)NO(4))(C(5)H(5)N)(3)(H(2)O)]·C(5)H(5)N}(n). The Co(2+) ion is six-coordinated by three N atoms, one water O atom and two O atoms from two ATPA ligands to form a distorted octa-hedral geometry. The two carboxyl-ate groups of ATPA act as bridging ligands connecting the Co(II) metal centers to form one-dimensional zigzag chains along the c axis, with Co-O distances in the range 2.104 (4)-2.135 (4) Å. The average Co-N distance is 2.171 Å. A classical O-H⋯N hydrogen bond is formed by the coordinating water mol-ecule and the pyridine solvent mol-ecule. The structure was refined from a racemically twinned crystal with a twin ratio of approximately 8:1.

catena-Poly[[[tetra-aqua-nickel(II)]-?-4,4'-bipyridyl-?N:N'] 3,3'-(p-phenyl-ene)diacrylate].

Project description:In the title compound, {[Ni(C(10)H(8)N(2))(H(2)O)(4)](C(12)H(8)O(4))}(n), the Ni(II), 4,4'-bipyridyl (bipy) and 3,3'-(p-phenyl-ene)diacrylate (L(2-)) moieties are situated on inversion centres. The bipy ligands bridge Ni(II) ions into positively charged polymeric chains along [101]. The Ni(II) atom is coordinated by two N atoms from two bipy ligands and four water mol-ecules in a distorted octa-hedral geometry. L(2-) anions inter-act with the polymeric chains via O-H?O hydrogen bonds, forming a three-dimensional supra-molecular network.

catena-Poly[[[aqua-(1,10-phenanthro-line)zinc(II)]-?-3,3'-(p-phenyl-ene)di-acrylato] hemihydrate].

Project description:In the title compound, {[Zn(C(12)H(8)O(4))(C(12)H(8)N(2))(H(2)O)]·0.5H(2)O}(n), each Zn(II) atom is six-coordinated by two N atoms from one 1,10-phenanthroline (phen), three carboxyl-ate O atoms from two different L ligands [H(2)L = 3,3'-(p-phenyl-ene)diacrylic acid] and one water mol-ecule in a distorted octa-hedral environment. The two L dianions are situated across inversion centres and bridge neighbouring Zn(II) centres, yielding a chain propagating parallel to [100]. O-H?O hydrogen bonds between the coordinated water molecule, the solvent water molecule (half-occupied) and the carboxylate O atoms further stabilize the structure.

Poly[[[μ-3,3'-(dimethyl-silanedi-yl)dibenzoato][μ-1,1'-(1,4-phenyl-ene)di-1H-imidazole]-zinc] monohydrate].

Project description:The asymmetric unit of the title compound, {[Zn(C₁₆H₁₆O₄Si)(C₁₂H₁₀N₄)]·H(2)O}(n), consists of one Zn(II) ion, two half 3,3'-(dimethyl-silanedi-yl)dibenzoate ligands and two half 1,1'-(1,4-phenyl-ene)di-1H-imidazole ligands. The Zn(II) ion is four-coordinated by two O atoms from two carboxlate ligands, two N atoms from two imidazole ligands. Two Zn(II) ions are bridged by two carboxyl-ate groups in chelating mode, generating a binuclear secondary building unit (SBU), which is further coordinated by two N atoms from two imidazole ligands in monodentate mode. Thus, the binuclear SBUs are further bridged by imidazole ligands in two different directions, giving rise to a chain. The water solvent mol-ecules are hydrogen bonded within the chain along the c axis.

catena-Poly[zinc-μ(3)-{3,3'-[(1,7-dioxa-4,10-diaza-cyclo-dodecane-4,10-di-yl)bis-(methyl-ene)]dibenzoato}].

Project description:The Zn(II) ion in the title compound, [Zn(C(24)H(28)N(2)O(6))](n), is located on a twofold rotation axis and is at the midpoint of a crown-4 moiety of 3,3'-[(1,7-dioxa-4,10-diaza-cyclo-dodecane-4,10-di-yl)bis-(methyl-ene)]dibenzoate anion. It is octahedrally coordinated by two N atoms and two O atoms of the crown moiety from one ligand and two carboxyl-ate O atoms from two bridging intra-chain ligands. Metallomacrocyclic rings are identified in the structure. The metallomacrocycle contains two Zn(II) ions and 14 atoms from the bridging ligands. Repetition of these units gives rise to an infinite zigzag chain along [101]. C-H⋯O hydrogen bonds occur.
