Aqua-(pyridine-3-carb-oxy-lic acid-?N)(pyridine-2,6-dicarboxyl-ato-?O,N,O)copper(II) monohydrate.

ABSTRACT: In the title Cu(II) complex, [Cu(C(7)H(3)NO(4))(C(6)H(5)NO(2))(H(2)O)]·H(2)O, the environment of the Cu(2+) ion is a distorted square pyramid with the axial site occupied by the O atom from the coordinated water mol-ecule and the square base formed by two O and two N atoms from the tridentate anion and the neutral monodentate pyridine-3-carboxylic acid ligand. O-H?O hydrogen bonds, as well as ?-? inter-actions [centroid-centroid distance = 3.945?(3)?Å] contribute to the stabilization of this structure.

Tris(3,5-dimethyl-1H-pyrazole-κN)(pyridine-2,6-dicarboxyl-ato-κO,N,O)cobalt(II) monohydrate.

Project description:The reaction of Co(NO(3))(2)·3H(2)O with pyridine-2,6-dicarboxylic acid and 3,5-dimethyl-1H-pyrazole in a 1:1:3 molar ratio affords the title complex, [Co(C(7)H(3)NO(4))(C(5)H(8)N(2))(3)]·H(2)O. The Co(II) atom is coordinated by one pyridine-2,6-dicarboxyl-ate chelating ligand and three 3,5-dimethyl-1H-pyrazole ligands in a distorted octa-hedral geometry. Hydrogen-bonding interactions involving the coordinated carboxylate group, 3,5-dimethyl-1H-pyrazole and water help to consolidate the crystal structure.

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

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.

Aqua-[1-(4-carb-oxy-phen-yl)-1H-imidazole-?N](pyridine-2,6-dicarboxyl-ato-?O,N,O)copper(II) monohydrate.

Project description:In the title complex, [Cu(C(7)H(3)NO(4))(C(10)H(8)N(2)O(2))(H(2)O)]·H(2)O, the Cu(II) ion is in a slightly distorted square-pyramidal geometry. Two carboxyl-ate O atoms and one pyridine N atom from a pyridine-2,6-dicarboxyl-ate ligand chelate the Cu(II) ion, forming two stable five-membered metalla rings. One imidazole N atom from a 1-(4-carb-oxy-phen-yl)imidazole ligand and one water mol-ecule complete the five-coordination. O-H?O hydrogen bonds involving the coordinated water mol-ecules and carboxyl-ate groups link the complex mol-ecules into chain-containing dinuclear macrocycles. O-H?O hydrogen bonds involving the uncoordinated water mol-ecules link the chains into a layer extending parallel to (10[Formula: see text]).

Project description:In the title compound, [CoNa(2)(C(7)H(3)NO(4))(2)(H(2)O)(2)](n), the Co(II) atom is coordinated by two pyridine N atoms and four carboxyl-ate O atoms from two doubly deprotonated pyridine-2,6-dicarboxyl-ate ligands in a distorted octa-hedral geometry.

The bis-(pyridine-2,6-dicarboxyl-ato)cobalt complex units are connected by Na(+) cations and bridging water mol-ecules into a three-dimensional coordination network. O-H?O hydrogen bonds are formed between the water mol-ecules and the carboxyl-ate O atoms.

Project description:In the centrosymmetric dinuclear complex anion of the title compound, (C(5)H(8)N(3))(2)[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)(2)]·4H(2)O, the Bi(III) atom is eight-coordinated in an N(2)O(6) environment and has a distorted bicapped trigonal-prismatic coordination environment. Extensive inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds lead to the stability of the crystal structure. Inter-actions between one C-H group of the 2,3-diamino-pyridinium [(2,3-dapyH)(+)] cation and the aromatic ring of the pyridine-2,6-dicarboxyl-ate (pydc) ligand (C-H⋯centroid distance = 2.78 Å) and π-π inter-actions between the (2,3-dapyH)(+) cations and between the (2,3-dapyH)(+) cation and the pydc ligand [centroid-centroid distances = 3.489 (5) and 3.694 (5) Å] are observed.

Project description:In the mononuclear title complex, [Cd(C(8)H(4)O(4))(C(8)H(7)N(3))(2)(H(2)O)], the Cd(II) atom is six-coordinated in a distorted octa-hedral geometry by four N atoms from two bidentate chelating 2-(1H-pyrazol-3-yl)pyridine ligands, one O atom from a benzene-1,2-dicarboxyl-ate ligand and one water mol-ecule. The mol-ecular structure features intra-molecular O-H⋯O and N-H⋯O hydrogen bonds. In the crystal structure, the complex mol-ecules are assembled into a two-dimensional supra-molecular layer parallel to (011) via O-H⋯O and N-H⋯O hydrogen bonds and π-π stacking inter-actions between the pyridyl and pyrazole rings [centroid-centroid distances = 3.544 (2) and 3.722 (3) Å].

The 1,3-di-4-pyridylpropane ligands link the Co(II) atoms into an infinite zigzag chain parallel to [010]. The chains are further linked through O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.
