(Quinoline-2-carboxyl-ato-?O)(quinoline-2-carb-oxy-lic acid-?O)bis-(quinoline-2-carb-oxy-lic acid-?N,O)potassium.

ABSTRACT: The K atom in the title complex, [K(C(10)H(6)NO(2))(C(10)H(7)NO(2))(3)], lies on a twofold rotation axis that relates one N,O-chelating quinoline-2-carb-oxy-lic acid to the other; their N and O atoms are cis to each other in the distorted octa-hedral coordination geometry. The K atom is also coordinated by another monodentate quinoline-2-carb-oxy-lic acid; the acid is disordered with respect to a monodentate quinoline-2-carboxyl-ate anion; the acid and anion are linked by an O-H?O hydrogen bond. An O-H?N hydrogen bond links adjacent mol-ecules into a linear chain structure along the a axis.

Di-?-aqua-bis-[aqua-(5-carboxyl-ato-1H-1,2,3-triazole-4-carb-oxy-lic acid-?(2) N (3),O (4))lithium].

Project description:The crystal structure of the title compound, [Li2(C4H2N3O4)2(H2O)4], contains centrosymmetric dinuclear mol-ecules in which two Li(I) ions are bridged by two water O atoms. The metal ion is coordinated by one N,O-bidentate ligand and three water O atoms (one of them is symmetry generated), with one of the bridging water O atoms in the apical position of a distorted square pyramid. The carboxyl-ate group that participates in coordination to the metal ion remains protonated; the other is deprotonated and coordination inactive. An intra-molecular O-H?O hydrogen bond between carboxyl-ate groups is observed. In the crystal, dimers are linked by O-H?O, O-H?N and N-H?O hydrogen bonds, generating a three-dimensional network.

Phenyl-hydrazinium (6-carb-oxy-pyridine-2-carboxyl-ato)(pyridine-2,6-dicarboxyl-ato)cobaltate(II)-pyridine-2,6-dicarb-oxy-lic acid-water (1/1/3).

Project description:The asymmetric unit of the title compound, (C(6)H(9)N(2))[Co(C(7)H(3)NO(4))(C(7)H(4)NO(4))]·C(7)H(5)NO(4)·3H(2)O, contains one (6-carb-oxy-pyridine-2-carboxyl-ato)(pyridine-2,6-dicarboxyl-ato)cobaltate(II) anion, one phenyl-hydrazinium cation, one pyridine-2,6-dicarb-oxy-lic acid mol-ecule and three uncoordin-ated water mol-ecules, part of which are disordered. The Co(II) ion is coordinated by a pyridine-2,6-dicarboxyl-ate ion and a 6-carb-oxy-pyridine-2-carboxyl-ate ligand almost perpendicular to each other [the angle between the least-squares planes is 87.38?(4)°] and is surrounded by two O atoms and two N atoms in the equatorial plane and two O atoms in axial positions, resulting in a distorted octa-hedral coordination geometry. There is an extensive three-dimensional network of O-H?O and N-H?O hydrogen bonds, which link the components.

catena-Poly[[[bis-(3-hy-droxy-adamantane-1-carboxyl-ato-?O)(3-hy-droxy-adamantane-1-carb-oxy-lic acid-?O)zinc(II)]-?(2)-4,4'-bipyridine] monohydrate].

Project description:In the title coordination polymer, {[Zn(C(11)H(15)O(3))(2)(C(10)H(8)N(2))(C(11)H(16)O(3))]·H(2)O}(n), the Zn(II) ion is five coordinated by two N atoms from two 4,4'-bipyridine (4,4'-bpy) mol-ecules and three O atoms from two 3-hy-droxy-adamantane-1-carboxyl-ate anions (L) and one 3-hy-droxy-adamantane-1-carb-oxy-lic acid (HL) mol-ecule. The resulting coordination polyhedron is a near regular ZnN(2)O(3) trigonal bipyramid, with the N atoms in axial sites. The 4,4'-bpy mol-ecules [dihedral angle between the aromatic rings = 17.2?(2)°] act as bridges, connecting the metal ions into an infinite polymeric chain propagating in [[Formula: see text]01]. O-H?O hydrogen bonds help to consolidate the packing.

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(pyridine-2-carboxyl-ato-κ2 N,O)copper(II)]-benzene-1,3,5-tri-carb-oxy-lic acid-water (1/2/2).

Project description:In the title complex, [Cu(C6H4O2N)2]·2C9H6O6·2H2O, the Cu2+ ion lies on a center of inversion and coordinates with symmetry related pyridine nitro-gen and carboxyl oxygen atoms from two pyridine-2-carb-oxy-lic acid anions, giving rise to a square-planar coordination geometry. There are weak axial bonds between Cu and an O atom of a symmetry-related trimesic acid moieties [Cu⋯O = 2.837 (2) Å] The Cu⋯O weak inter-actions and hydrogen bonds stabilize the whole structure.

An intra-molecular O-H?O hydrogen bond occurs. In the crystal, inter-molecular N-H?O and O-H?O hydrogen bonds form a three-dimensional network, which consolidates the packing.

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.
