Bis(?-hydroxido-?(2) O:O)bis[bis(5-car-boxy-pyridine-2-carboxyl-ato-?(2) N,O (2))iron(III)] dihydrate.

ABSTRACT: The complete binuclear complex in [Fe2(C7H4NO4)4(OH)2]·2H2O, is generated by the application twofold symmetry. The Fe(III) atom is coordinated by the O atoms of two bridging hydroxyl groups and by two N and two O atoms from two pyridine-2,5-di-carboxyl-ato ligands, forming a distorted octa-hedral geometry. The Fe?Fe separation within the dinuclear complex is 3.0657?(4)?Å. In the crystal, O-H?O and C-H?O hydrogen-bonding inter-actions connect the mol-ecules into a three-dimensional supra-molecular network.

Project description:The title compound, {[Cu(C(17)H(11)N(2)O(3))(2)(H(2)O)]·2H(2)O}(n), is a two-dimensional polymer. The Cu(2+) ion lies on the crystallographic twofold axis. The coordination sphere of the Cu(2+) ion can be described as a distorted square pyramid. All of the H atoms in the amide group and lattice water mol-ecules participate in O-H⋯O or N-H⋯O hydrogen bonding to strengthen the two-dimensioal framework of the polymer.

Project description:The structure of the title compound, [Pb(2)(C(5)H(3)N(2)O(2))(4)(H(2)O)(6)]·2H(2)O, is composed of dimeric mol-ecules in which two symmetry-related Pb(2+) ions are bridged by a pair of two pyridazine-4-carboxyl-ate ligand mol-ecules via both heterocyclic N atoms and two water O atoms. Each Pb(2+) ion is also coordinated by two carboxyl-ate O atoms and three water O atoms, leading to a highly irregular coordination polyhedron around Pb(2+). The dimers are inter-connected by hydrogen bonds between coordinated and uncoordinated water mol-ecules and the carboxyl-ate O atoms. O-H⋯N inter-actions are also present.

Poly[[tetra-aqua-bis-(μ(3)-pyridine-2,6-dicarboxyl-ato)(μ(2)-pyridine-2,6-dicarboxyl-ato)dilanthanum(III)] dihydrate].

Project description:There are two independent La(III) cations in the polymeric title compound, {[La(2)(C(7)H(3)NO(4))(3)(H(2)O)(4)]·2H(2)O}(n). One is nine-coordinated in an LaN(2)O(7) tricapped trigonal-prismatic geometry formed by three pyridine-2,6-dicarboxyl-ate anions and two water mol-ecules, while the other is ten-coordinated in an LaNO(9) bicapped square-anti-prismatic geometry formed by four pyridine-2,6-dicarboxyl-ate anions and two water mol-ecules. The two La(III) cations are separated by a non-bonding distance of 5.026 (3) Å. The pyridine-2,6-dicarboxyl-ate anions bridge the La(III) cations, forming a three-dimensional polymeric complex. The crystal structure contains extensive classical O-H⋯O hydrogen bonds and weak inter-molecular C-H⋯O hydrogen bonds. The crystal structure is further consolidated by π-π stacking between pyridine rings, the shortest centroid-centroid distance between parallel pyridine rings being 3.700 (5) Å.

Poly[piperazinediium [aqua-bis(μ-pyridine-2,5-dicarboxyl-ato)zincate] dihydrate].

Project description:The polymeric title compound, {(C(4)H(12)N(2))[Zn(C(7)H(3)NO(4))(2)(H(2)O)]·2H(2)O}(n), was obtained by the reaction of zinc(II) nitrate hexa-hydrate with the proton-transfer compound (pipzH(2))(py-2,5-dc) (where pipz is piperazine and py-2,5-dcH(2) is pyridine-2,5-dicarboxylic acid) in aqueous solution. Each Zn(II) atom is coordinated in a distorted octa-hedral geometry by four O atoms and two N atoms from one water mol-ecule and two (py-2,5-dc)(2-) ligands, which also act as bridging ligands between Zn(II) atoms. π-π Stacking inter-actions between two aromatic rings of (py-2,5-dc)(2-) fragments, with centroid-centroid distances of 3.4747 (7) and 3.7081 (7) Å are observed. The crystal structure is stabilized by O-H⋯O and N-H⋯O hydrogen bonds.

Bis(μ-pyridazine-3-carboxyl-ato-κO:O')bis-[aqua-dioxido(pyridazine-3-carboxyl-ato-κN,O)uranium(VI)] dihydrate.

Project description:The structure of the binuclear title complex, [U(2)(C(5)H(3)N(2)O(2))(4)O(4)(H(2)O)(2)]·2H(2)O, is composed of centrosymmetric dimers in which each UO(2) (2+) ion is coordinated by two ligand mol-ecules. One donates its N,O-bonding group and the other donates both carboxyl-ate O atoms. Each of the latter bridges adjacent uranyl ions. The coordination environment of the metal center is a distorted penta-gonal bipyramid. The dimers are inter-connected by O-H⋯O hydrogen bonds between coordinated and uncoordinated water mol-ecules and carboxyl-ate O atoms. An intra-molecular O-H⋯N inter-action is also present.

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.

Bis(μ-2-phenyl-quinoline-4-carboxyl-ato)bis-[aqua-(1,10-phenanthroline)(2-phenyl-quinoline-4-carboxyl-ato)manganese(II)] dihydrate.

Project description:In the centrosymmetric dinuclear title complex, [Mn(2)(C(16)H(10)NO(2))(4)(C(12)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, the Mn(II) cation is in a distorted octa-hedral coordination geometry defined by two N atoms from a 1,10-phenanthroline ligand, one water O atom and three O atoms from three 2-phenyl-quinoline-4-carboxyl-ate anions. A pair of 2-phenyl-quinoline-4-carboxyl-ate anions bridge two Mn cations, forming the dinuclear mol-ecule. An intra-moleculr O-H⋯O hydrogen bond occurs. Inter-molecular O-H⋯O and O-H⋯N hydrogen bonds are present in the crystal structure.

catena-Poly[[[diaqua-terbium(III)]-μ-6-carboxy-nicotinato-μ-pyridine-2,5-di-carboxyl-ato] dihydrate].

Project description:The title compound, {[Tb(C(7)H(3)NO(4))(C(7)H(4)NO(4))(H(2)O)(2)]·2H(2)O}(n), is isotypic with the analogous Tm(III) compound [Li, Zhang, Wang & Bai (2009). Acta Cryst. E65, m411]. The Tb(III) atom is octa-coordinated by two water mol-ecules and by four carboxyl-ate O atoms and two pyridyl N atoms from two pyridine-2,5-dicarboxyl-ate (2,5-pydc) and two 6-carboxy-nicotinate (2,5-Hpydc) ligands. The 2,5-pydc and 2,5-Hpydc ligands bridge Tb(III) atoms, generating helical coordination polymers along [001]. An extensive network of O-H⋯O hydrogen bonds is formed between the coordination polymers and the uncoordinated water mol-ecules. The refined Flack parameter of 0.54 (2) suggests inversion twinning.
