Poly[[triaqua-(?(3)-4-oxidopyridine-2,6-dicarboxyl-ato)terbium(III)] monohydrate].

ABSTRACT: In the title coordination polymer, {[Tb(C(7)H(2)NO(5))(H(2)O)(3)]·H(2)O}(n), the Tb(III) atom is eight-coordinated by a tridentate 4-oxidopyridine-2,6-dicarboxyl-ate trianion, two adjacent monodentate anions and three water mol-ecules, forming a distorted bicapped trigonal-prismatic TbNO(7) coordination environment. The anions bridge adjacent Tb(III) ions into double chains. Adjacent chains are further connected into sheets parallel to (10). O-H?O hydrogen bonds involving both coordinated and uncoordinated water mol-ecules generate a three-dimensional network.

Project description:The asymmetric unit of the title compound, {[Tb(C(8)H(2)NO(6))(H(2)O)(3)]·H(2)O}(n), contains one Tb(III) ion, one pyridine-2,4,6-tricarboxyl-ate (ptc) anion, three aqua ligands and one lattice water mol-ecule.

The ptc ligands bridge the Tb(III) ions into a two-dimensional polymeric framework parallel to (100). An extensive O-H?O hydrogen-bonding network consolidates the crystal packing.

Poly[piperazinediium [[aqua-bismuth-ate(III)]-di-?-pyridine-2,6-dicarboxyl-ato-bis-muthate(III)-di-?-pyridine-2,6-dicarboxyl-ato] monohydrate].

Project description:The title compound, {(C(4)H(12)N(2))[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)]·H(2)O}(n) or {(pipzH(2))[Bi(2)(pydc)(4)(H(2)O)]·H(2)O}(n), where pydcH(2) is pyridine-2,6-dicarboxylic acid and pipz is piperazine, was obtained by reaction of Bi(NO(3))(3)·5H(2)O with (pipzH(2))(pydc-H)(2)·3H(2)O in a 1:2 molar ratio in aqueous solution. There are two independent Bi(III) atoms in the structure, one of which is eight-coordinate with a distorted bicapped trigonal-prismatic geometry, and another which is nine-coordinate with a distorted tricapped trigonal-prismatic geometry. The carboxyl-ate groups of the (pydc)(2-) ligands link dinuclear [Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)](2-) units into one-dimensional coordin-ation polymers. The pipzH(2) (2+) cations (site symmetry ) and non-coordinated water mol-ecules lie between these polymers, forming N-H?O and O-H?O hydrogen bonds to the O atoms of the carboxylate groups.

Poly[triaqua-tris-(?(4)-pyridine-3,5-dicarboxyl-ato)dicerium(III)].

Project description:The asymmetric unit of the title compound, [Ce(2)(C(7)H(3)NO(4))(3)(H(2)O)(3)](n), contains two Ce(III) cations, three pyridine-3,5-dicarboxyl-ate (pyd) anions and three coordinated water mol-ecules. One Ce(III) cation is coordinated by seven carboxyl-ate O atoms from six pyd anions and two water mol-ecules in a square-face-capped square-anti-prismatic geometry. Another Ce(III) cation is coordinated by seven O atoms from six pdy anions and one water mol-ecule in a bicapped trigonal-prismatic geometry. The pdy anions bridge the Ce(III) cations, forming the three-dimensional polymeric structure. The crystal structure contains extensive O-H?O, O-H?N and weak C-H?O hydrogen bonds. ?-? stacking is present in the crystal structure, the shortest centroid-centroid distance between parallel pyridine rings being 3.509?(4)?Å.

Project description:The Cu atom in the title complex, {[Cu(C(6)H(2)N(2)O(4))(H(2)O)(3)]·H(2)O}(n) or {[Cu(L)(H(2)O)(3)]·H(2)O}(n) (L is pyrazine-2,3-dicarbox-yl-ate), displays octa-hedral coordination formed by the ligand L and three coordinated water mol-ecules. The ligand L is tridentate, with one N atom of the pyrazine ring and one O atom of one carboxyl-ate group forming a chelate ring, whereas one O atom from the second carboxyl-ate group is coordinated to another Cu atom. The ligand L links mol-ecules to form an infinite chain parallel to the [101] direction. The chains are further linked through O-H⋯O and O-H⋯N hydrogen bonds involving the water mol-ecules to build up a three-dimensional network.

Project description:The title compound, {[Cu(C(12)H(6)N(2)O(4))(H(2)O)(3)]·H(2)O}(n), was synthesized under hydro-thermal conditions. The Cu(2+) ion is six-coordinated by three water O atoms, and two N atoms and one O atom of the 2,2'-bipyridine-3,3'-dicarboxyl-ate bridging ligand in a sligthly distorted octa-hedral environment. The 2,2-bipyridine-3,3'-dicarboxyl-ate bridges link the Cu(2+) ions into chains along the b-axis direction. These chains are further linked by O-H?O hydrogen bonds involving the water solvent mol-ecules, forming a three-dimensional framework.
