Tris(6-carb-oxy-pyridine-2-carboxyl-ato)terbium(III) 2.75-hydrate.

ABSTRACT: In the title compound, [Tb(C(7)H(4)NO(4))(3)]·2.75H(2)O, the Tb(3+) atom is coordinated by three tridentate 6-carb-oxy-pyridine-2-carboxyl-ate ligands and lies on a crystallographic threefold rotation axis. The coordination polyhedron around Tb(III) adopts a distorted tricapped trigonal-prismatic geometry. Disordered water mol-ecules with partial occupancy are also present in the crystal, one of which is associated with each of the carboxyl-ate O atoms of the complex unit.

Bis-(μ-pyridine-2,3-dicarboxyl-ato)bis-[aqua-(3-carb-oxy-pyridine-2-carboxyl-ato)indium(III)] tetra-hydrate.

Project description:In the binuclear centrosymmetric title compound, [In(2)(C(7)H(3)NO(4))(2)(C(7)H(4)NO(4))(2)(H(2)O)(2)]·4H(2)O, which contains both pyridine-2,3-dicarboxyl-ate and 3-carb-oxy-pyridine-2-carboxyl-ate ligands, the In(III) atom is six-coordinated in a distorted octa-hedral geometry. One pyridine ligand is N,O-chelated while the other is N,O-chelated and at the same time bridging to the other via the second carboxyl group. In the crystal, an extensive O-H⋯O hydrogen-bonding network, involving the coordinated and lattice water mol-ecules and the carboxyl groups of the ligands, together with C-H⋯O and π-π inter-actions [centroid-centroid distance = 3.793 (1) Å], leads to the formation of a three-dimensional structure.

Project description:In the title compound, [Ce(C(7)H(3)NO(4))(C(7)H(4)NO(4))(H(2)O)(5)]·4H(2)O, the Ce(3+) ion is nine-coordinated by two O atoms and two N atoms from one single and from one double deprotonated pyridine-2,5-dicarboxyl-ate ligand and five water mol-ecules in a distorted monocapped square-anti-prismatic geometry. In the crystal, extensive O-H?O hydrogen-bonding inter-actions result in a three-dimensional supra-molecular architecture.

Hexaaqua-zinc(II) bis-[tris-(3-carb-oxy-pyridine-2-carboxyl-ato)zincate(II)].

Project description:The title compound, [Zn(H(2)O)(6)][Zn(C(7)H(4)NO(4))(3)](2), consists of two [Zn(py-2,3-dcH)(3)](-) anions (py-2,3-dcH is 3-carboxy-pyridine-2-carboxylate) and one [Zn(H(2)O)(6)](2+) cation. The anion is a six-coordinate complex located on a threefold rotation axis with a slightly distorted octa-hedral geometry around Zn(2+) ion. The cation is also six-coordinate with an octa-hedral geometry around the Zn atom, located at a axis. Non-covalent inter-actions such as π-π stacking [centroid-centroid distance = 3.828 (4)Å] and O-H⋯O hydrogen bonds play important roles in stabilizing the supra-molecular structure.

Guanidinium hexa-aqua-zinc(II) bis[tris-(3-carb-oxy-pyridine-2-carboxyl-ato)zincate].

Project description:In the title mol-ecular salt, (CH(6)N(3))(1.30)[Zn(H(2)O)(6)](0.35)[Zn(C(7)H(4)NO(4))(3)](2), the Zn(II) atom (site symmetry 3) in the anion is coordinated by three N,O-bidentate 3-carb-oxy-pyridine-2-carboxyl-ate monoanions to generate a fac-ZnN(3)O(3) octa-hedral coordination geometry. The guanidinium cation (the C atom has site symmetry 3) and the octa-hedral hexa-aqua-zinc(II) dication (the Zn(2+) cation has site symmetry -3) are occupationally disordered in a 1.30:0.35 ratio. In the crystal, the components are linked by O-H?O and N-H?O hydrogen bonds to generate infinite (001) sheets. Weak aromatic ?-? stacking [centroid-centroid distance = 3.797?(8)?Å] is also observed in the crystal.

Tetra-kis(1,10-phenanthroline)bis-(?-pyridine-2,6-dicarboxyl-ato)(pyridine-2,6-di-carboxyl-ato)dicopper(II)terbium(III) nitrate tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Cu(2)Tb(C(7)H(3)NO(4))(3)(C(12)H(8)N(2))(4)]NO(3)·4H(2)O, consists of one-half of the C(2)-symmetric trinuclear coordination cation, one-half of the C(2)-symmetric nitrate anion and two water mol-ecules. In the coordination cation, the Cu(II) atom is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from a bridging-chelating carboxyl-ate group of the pyridine-2,6-dicarboxyl-ate anion, completing a distorted N(4)O(2) octa-hedral coordination environment. The Tb(III) atom, located on a twofold rotation axis, is nine-coordinated by three tridentate pyridine-2,6-dicarboxyl-ate anions forming an N(3)O(6) donor set. The intra-molecular Cu?Tb distance of 5.0592?(11)?Å indicates weak inter-actions between the Cu(II) and Tb(III) atoms. The coordination cations, nitrate anions and water mol-ecules are connected via O-H?O hydrogen bonds into layers parallel to the (001) plane. Moreover, there are extensive ?-? stacking inter-actions [centroid-centroid distances = 4.332?(7) and 3.878?(5)?Å] between the phenanthroline ligands and between phenanthroline and pyridine-2,6-dicarboxyl-ate ligands.

Tris(piperazinediium) bis-[tris-(pyridine-2,6-dicarboxyl-ato)neodymate(III)] 15.33-hydrate.

Project description:The title compound, (C(4)H(12)N(2))(3)[Nd(C(7)H(3)NO(4))(3)](2)·15.33H(2)O or (pipzH(2))(3)[Nd(pydc)(3)](2)·15.33H(2)O (in which pipz is piperazine and pydcH(2) is pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of NdCl(3)·6H(2)O with the proton-transfer compound (pipzH(2))(pydc) in aqueous solution. The nine donor atoms of the three pydc(2-) ligands form a distorted tricapped trigonal-prismatic arrangement around the Nd(III) center. Considerable C-O⋯π stacking inter-actions between CO groups of carboxyl-ate fragments and aromatic rings of pydc(2-) with distances of 3.135 (5)-3.255 (5) Å are observed. In the crystal structure, a wide range of hydrogen-bonding [of the types O-H⋯O, N-H⋯O and C-H⋯O, with D⋯A distances ranging from 2.608 (10) to 3.278 (7) Å], ion-pairing and C-O⋯π stacking interactions connect the various components into a supra-molecular structure. There is a high degree of solvent disorder in the structure; the occupancies of five water molecules refined to 0.6, 0.5, 0.4, 0.25 and 0.25.

fac-Tris(pyridine-2-carboxyl-ato-?N,O)cobalt(III).

Project description:In the title compound, [Co(C(6)H(4)NO(2))(3)], the Co(III) ion lies on a threefold rotation axis and is in a distorted octa-hedral environment defined by three N and three O donor atoms from three fac-disposed pyridine-2-carboxyl-ate ligands. The ligands are coordinated in a chelate fashion, forming three five-membered rings. In the crystal, translationally related complex molecules are organized into columns along [001] via C-H?O hydrogen bonds.

Triimidazolium tris-(pyridine-2,6-di-carboxyl-ato)dysprosate(III) trihydrate.

Project description:The structure of the title compound, (C(3)N(2)H(5))(3)[Dy(C(7)H(3)NO(4))(3)]·3H(2)O, contains a mononuclear Dy(III) complex with the rare earth metal cation in a distorted tricapped trigonal-prismatic environment. The Dy(III) ion is in each case O,N,O'-chelated by three tridentate pyridine-2,6-dicarboxyl-ate anions. Three protonated imidazole mol-ecules act as counter-cations and three lattice water mol-ecules are also present. Numerous N-H⋯O and O-H⋯O hydrogen bonding inter-actions, some of which are bifurcated, help to stabilize the packing of the structure.

Poly[[penta-aqua-(?(4)-pyridine-2,4,6-tri-carboxyl-ato)(?(3)-pyridine-2,4,6-tri-carboxyl-ato)diterbium(III)] mono-hydrate].

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.
