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

ABSTRACT: 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 Tb(III) ion is nine coordinated by one N and five O atoms from three ptc ligands and by three O atoms from the three aqua ligands in a distorted bicapped trigonal-prismatic geometry. 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.

Project description: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.

Poly[?(3)-hydroxido-?-(pyridine-2,4,6-tricarboxyl-ato)-dilead(II)].

Project description:The asymmetric unit of the title coordination polymer, [Pb(2)(C(8)H(2)NO(6))(OH)](n), contains two crystallographically independent Pb(II) ions, one pyridine-2,4,6-tricarboxyl-ate (ptc) trianion and one hydroxide anion. One of the Pb(II) atoms is coordinated by one pyridine N and four carboxyl-ate O atoms from the ptc trianion and a hydroxide O atom in a distorted octa-hedral geometry. The other Pb(II) atom is five-coordinated by three carboxyl-ate O atoms and two hydroxide O atoms in a distorted tetra-gonal-pyramidal geometry. Four neighbouring Pb(II) atoms are bridged through two ?(3)-hydroxide ligands, forming the centrosymmetric Pb(4)(OH)(2) core. The three-dimensional structure is further achieved through bridging carboxyl-ate groups. There are also O-H?O hydrogen bonds between the hydroxide ligand and the carboxyl-ate group.

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.

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 three-dimensional title coordination polymer, {[Tb(2)(C(8)H(2)NO(6))(2)(H(2)O)(5)]·H(2)O}(n), was hydro-thermally synthesized by reacting the corresponding rare-earth salt with pyridine-2,4,6-tricarb-oxy-lic acid (H(3)ptc). There are two independent Tb(III) atoms in the structure, one of which is nine-coordinated, forming a monocapped NO(8) square-anti-prism and the other is eight-coordinated exhibiting a 4,4-bicapped NO(7) trigonal-prismatic environment. The complex units are inter-connected through the ptc(3-) anions acting in different coordination modes, resulting in a three-dimensional coordin-ation polymer. The crystal structure features extensive O-H?O hydrogen bonds.
