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

ABSTRACT: 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.

Crystal structure of catena-poly[[[di-aqua-bis-(2,4,6-tri-methyl-benzoato-κO)cobalt(II)]-μ-aqua-κ2O:O] dihydrate].

Project description:The asymmetric unit of the title one-dimensional polymeric compound, {[Co(C10H11O2)2(H2O)3]·2H2O} n , contains one CoII cation situated on a centre of inversion, one-half of a coordinating water mol-ecule, one 2,4,6-tri-methyl-benzoate (TMB) anion together with one coordinating and one non-coordinating water mol-ecule; the TMB anion acts as a monodentate ligand. In the anion, the carboxyl-ate group is twisted away from the attached benzene ring by 84.9 (2)°. The CoII atom is coordinated by two TMB anions and two water mol-ecules in the basal plane, while another water mol-ecule bridges the CoII atoms in the axial directions, forming polymeric chains running along [001]. The coordination environment for the CoII cation is a slightly distorted octa-hedron. The coordinating and bridging water mol-ecules link to the carboxyl-ate groups via intra- and inter-molecular O-H⋯O hydrogen bonds, enclosing S(6) ring motifs, while the coordinating, bridging and non-coordinating water mol-ecules link to the carboxyl-ate groups and the coordinating water mol-ecules link to the non-coordinating water mol-ecules via O-H⋯O hydrogen bonds, enclosing R22(8) and R33(8) ring motifs. Weak C-H⋯O and C-H⋯π inter-actions may further stabilize the crystal structure.

Project description:The title compound, {[Co(C(2)H(5)COO)(2)(H(2)O)]·H(2)O}(n), was synthesized by the reaction of cobalt(II) carbonate hydrate with aqueous propionic acid. The structure consists of polymeric infinite linear chains with composition [Co(C(2)H(5)COO)(4/2)(H(2)O)(2/2)](∞) running along [010]. The chains are formed by Co(2+) ions linked with bridging propionate groups and water mol-ecules, with a Co⋯Co distance along the chains of 3.2587 (9) Å. The Co(2+) ion is six-coordinated in a strongly distorted octa-hedral geometry. The chains are connected to each other by a network of O-H⋯O hydrogen bonds involving solvent water mol-ecules.

catena-Poly[[cobalt(II)-μ-aqua-di-μ-butano-ato-κO:O';κO:O] 0.7-hydrate].

Project description:In the title coordination polymer, {[Co(C(3)H(7)COO)(2)(H(2)O)]·0.7H(2)O}(n), the Co(2+) cation is coordinated by four bridging butano-ate anions and two bridging water mol-ecules in a severely distorted octa-hedral geometry. The Co(2+) cations are linked by means of bridging ligands into polymeric chains along [010]. These chains are further connected to each other through hydrogen bonds involving partially occupied disordered water mol-ecules; thus, sheets parallel to (001) are formed. One of the positions of disordered water O atom lies on a twofold axis. Two atoms of the aliphatic chain of one of the butanoate anions are disordered over two positions each.

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

Project description: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.

catena-Poly[[aqua-(2-iodo-benzoato-κO)cobalt(II)]-μ-aqua-μ-2-iodo-benzoato-κ(2)O:O'].

Project description:The asymmetric unit of the polymeric title compound, [Co(C(7)H(4)IO(2))(2)(H(2)O)(2)](n), contains one Co(II) cation, two iodo-benzoate anions and two water mol-ecules. One iodo-benzoate anion and one water mol-ecule bridge adjacent Co cations, forming a polymeric chain running along the a axis, while the other iodo-benzoate anion and water mol-ecule coordinate in a monodentate manner to the Co(II) cation, completing the slightly distorted octa-hedral geometry. In the two independent anionic ligands, the carboxyl-ate groups are twisted away from the attached benzene rings by 51.38 (18) and 39.89 (11)°, and the two benzene rings are nearly perpendicular to each other with a dihedral angle of 86.09 (10)°. Intra-molecular O-H⋯O hydrogen bonds between coordinating water mol-ecules and adjacent carboxyl-ate O atoms help to stabilize the mol-ecular structure. In the crystal, weak C-H⋯O hydrogen bonds link the polymeric chains into a three-dimentional supra-molecular network.

catena-Poly[[diaqua-bis-(3-methyl-pyridine-κN)cobalt(II)]-μ-sulfato-κO:O'].

Project description:The environment of the Co(II) ion in the title compound, [Co(SO(4))(C(6)H(7)N)(2)(H(2)O)(2)](n), exhibits an octa-hedral configuration with the two 3-methyl-pyridine ligands lying in cis positions with respect to each other and trans to the two coordinated water mol-ecules. The axial positions are occupied by O atoms of the sulfate ions. Co and S atoms occupy special positions (twofold axis, Wyckoff position 4c). Neighboring Co(II) ions are covalently connected with each other through the sulfate ions, thus creating infinite polymeric chains that run along the c axis. The water mol-ecules are connected with neighboring sulfate ions through strong O-H⋯O hydrogen bonds. Intra-molecular hydrogen bonds parallel to the propagation direction of the chains stabilize the polymeric chains, and inter-molecular hydrogen bonds between chains connect neighboring chains with each other, thus leading to polymeric double chains.

catena-Poly[[[aqua-(pyridine-2,6-dicarboxyl-ato N-oxide-κO,O)cobalt(II)]-μ-1,3-di-4-pyridylpropane-κN:N'] dihydrate].

Project description:In the title compound, {[Co(C(7)H(3)NO(5))(C(13)H(14)N(2))(H(2)O)]·2H(2)O}(n), the Co(II) atom is coordinated by two O atoms from a pyridine-2,6-dicarboxyl-ate N-oxide ligand, two N atoms from two 1,3-di-4-pyridylpropane ligands and one water mol-ecule, and displays a distorted square-pyramidal coordination geometry. The 1,3-di-4-pyridylpropane ligands link the Co(II) atoms into an infinite zigzag chain parallel to [010]. The chains are further linked through O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.

Project description:In the crystal structure of the title complex, {[Mn(C(11)H(14)NO(2))(2)(H(2)O)(3)]·2H(2)O}(n), the two independent Mn(II) atoms are located on a centre of symmetry and coordinated by two 4-(diethyl-amino)benzoate (DEAB) anions and two water mol-ecules in the basal plane while another water mol-ecule bridges the Mn atoms in the apical directions, forming polymeric chains. The dihedral angles between the carboxyl-ate groups and the adjacent benzene rings are 11.33 (13) and 10.90 (9)° and the benzene rings are oriented at a dihedral angle of 67.88 (6)°. The uncoordinated water mol-ecules link the carboxyl-ate groups and coordinated water mol-ecules via O-H⋯O hydrogen bonding. Weak C-H⋯π inter-actions are also found in the crystal structure.

catena-Poly[[[tetra-aqua-cobalt(II)]-μ-4,4'-bipyridine-κN:N'] pyridine-3,5-dicarboxyl-ate trihydrate].

Project description:The crystal structure of the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(3)NO(4))·3H(2)O}(n), consists of Co(II) polymeric complex cations, uncoordinated pyridine-3,5-dicarboxyl-ate anions and lattice water mol-ecules. The Co(II) cation is coordinated by two N atoms from two 4,4'-bipyridine ligands and four water mol-ecules in a distorted octa-hedral geometry. The 4,4'-bipyridine ligands bridge Co cations, forming a polymeric chain running along the b axis. The two pyridine rings of the 4,4'-biyridine are twisted to each other by a dihedral angle of 8.95 (9)°. Extensive O-H⋯O hydrogen bonding network is present in the crystal structure.

catena-Poly[potassium-di-μ-aqua-μ-4-(5-tetra-zolio)pyridine].

Project description:The title compound, [K(C(6)H(4)N(5))(H(2)O)(2)](n), was synthesized by hydro-thermal reaction of KOH with 4-(5-tetra-zolio)pyridine. The K atom has a distorted octa-hedral coordination environment and is coordinated by two axial N atoms from the organic ligand and by four water mol-ecules in the equatorial plane. The mol-ecules as a whole are located on crystallographic mirror planes; the K atom is also located on an inversion center. Both the water mol-ecules and the organic ligands act as bridges to link symmetrically the adjacent K atoms into polymeric chains parallel to the c axis. O-H⋯N hydrogen bonds involving the water O atoms and aromatic π-π inter-actions [centroid-centroid distance 3.80 (2) Å] between the pyridine and tetra-zole rings build up an infinite three-dimensional network.
