Poly[bis-(μ-2,6-dimethyl-pyridinium-3,5-dicarboxyl-ato-κO:O)copper(II)].

ABSTRACT: In the title coordination polymer, [Cu(C(9)H(8)NO(4))(2)](n), the Cu atom, located on a twofold rotation axis, is four coordinate in a distorted square-planar environment. Each 2,6-dimethyl-pyridinium-3,5-dicarboxyl-ate anion bridges two Cu atoms, forming a two-dimensional coordination polymer. A three-dimensional supra-molecular network is built from N-H⋯O hydrogen bonds involving the pyridinium NH and the carboxyl COO groups.

Project description:The title compound, {(C(10)H(10)N(2))[Ce(2)(C(7)H(3)NO(4))(4)(H(2)O)(4)]·5H(2)O}(n), is composed of a one-dimensional anionic complex, a doubly protonated 4,4'-bipyridine mol-ecule as a counter-ion and five uncoordinated water mol-ecules. The anion bears two nine-coordinate Ce(III) ions, each with a distorted tricapped trigonal-prismatic geometry. In the crystal, inter-molecular C-H⋯O, N-H⋯O and O-H⋯O hydrogen bonds, as well as π-π inter-actions with centroid-centroid distances of 3.514 (3) Å connect the various components into a supra-molecular structure.

Project description:The title compound, [Cu(3)(C(7)H(3)NO(4))(4)(C(2)H(8)N(2))(2)]·C(2)H(8)N(2)·4H(2)O, was obtained by the reaction of copper(II) acetate dihydrate with pyridine-2,6-dicarb-oxy-lic acid (H(2)dipic) and ethyl-enediamine (en) in an aqueous solution. All of the Cu(II) atoms in the trinuclear centrosymmetric title complex are six-coordinated in a distorted octa-hedral geometry with N(2)O(4) and N(4)O(2) environments for the outer and central Cu(II) atoms, respectively. Various inter-actions, including numerous O-H⋯O and C-H⋯O hydrogen bonds and C-O⋯π stacking of the pyridine and carboxyl-ate groups [O⋯centroid distances = 3.669 (2) and 3.668 (2) Å] are observed in the crystal structure.

Bis[triaqua-(1H-1,2,4-triazole-3,5-dicarboxyl-ato-κO,N)copper(II)] di-μ-aqua-bis-[diaqua-(1H-1,2,4-triazole-3,5-dicarboxyl-ato-κO,N)copper(II)].

Project description:In the title compound, [Cu(C(4)HN(3)O(4))(H(2)O)(3)](2)[Cu(2)(C(4)HN(3)O(4))(2)(H(2)O)(6)], both monomeric and dimeric mol-ecules are present in the solid state. In the monomeric compound, the Cu(II) atom is five-coordinated in a square-pyramidal configuration by one O atom and one N atom from one 1H-1,2,4-triazole-3,5-dicarboxyl-ate (TZDCA(2-)) ligand and three O atoms from water mol-ecules. In the centrosymmetric binuclear complex, each Cu(II) atom is six-coordinated in an octa-hedral geometry by one O atom and one N atom from one TZDCA(2-) ligand and four O atoms from water mol-ecules, two of which bridge the Cu(II) atoms. In the structure, there are intra-molecular O-H⋯O and N-H⋯O hydrogen bonds, and in the crystal, inter-molecular O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds link symmetry-related mol-ecules, forming a three-dimensional supra-molecular structure.

catena-Poly[[(3,5-dicarb-oxy-pyrazine-2,6-dicarboxyl-ato-κO,N,O)lithium(I)]-μ-aqua-[triaqua-lithium(I)]-μ-aqua].

Project description:The title coordination polymer, [Li(2)(C(8)H(2)N(2)O(8))(H(2)O)(5)](n) contains two symmetry-independent Li(+) ions; one is coordin-ated by five water O atoms, the other by an O,N,O'-tridentate doubly deprotonated pyrazine-2,3,5,6-tetra-carboxyl-ate ligand and two water O atoms. Water mol-ecules bridge adjacent Li(+) ions into ribbons propagating in [100]; an alternative analysis of the structure considers it to contain alternating [Li(C(8)H(2)N(2)O(8))(H(2)O)(2)](-) anions and [Li(H(2)O)(3)](+) cations. In the polymeric model, both lithium ions show distorted trigonal-bipyramidal coordination geometries. Within the ligand, the carboxyl H atoms participate in short, almost symmetric O⋯H⋯O hydrogen bonds in which the non-coordinated carboxyl-ate O atoms are donors and acceptors. In the crystal, the ribbons inter-act via a network of O-H⋯O hydrogen bonds in which the coordinated water mol-ecules act as donors and ligand carboxyl-ate O atoms as acceptors.

Poly[hexa-aqua-bis(μ(3)-naphthalene-2,6-dicarboxyl-ato)(μ(2)-naphthalene-2,6-dicarboxyl-ato)diholmium(III)].

Project description:The crystal structure of the title compound, [Ho(2)(C(12)H(6)O(4))(3)(H(2)O)(6)](n), contains binuclear centrosymmetric {Ho(2)O(2)(CO(2))(4)(H(2)O)(6)} cores inter-connected via the naphthalene-2,6-dicarboxyl-ate (NDC(2-)) bridging ligands into a two-dimensional neutral plane net, ∞(2)[Ho(2)(NDC)(3)(H(2)O)(6)], exhibiting a typical (4,4)-topology. Inter-actions between adjacent layers are assured by a series of C-H⋯π contacts and a number of strong and highly directional O-H⋯O hydrogen bonds involving the coordinated water mol-ecules and neighbouring coordinated carboxyl-ate groups. One NDC(2-) bridging ligand has its centroid located at a crystallographic centre of inversion.

Poly[diaqua-(μ(3)-pyridine-3,5-dicarboxyl-ato-κN:O:O)copper(II)].

Project description:The title complex, [Cu(C(7)H(3)NO(4))(H(2)O)(2)](n), was prepared under hydro-thermal reaction conditions. In the crystal structure, the Cu(II) cation is located on a twofold rotation axis and is coordinated by two carboxyl-ate O atoms and one N atom from three pyridine-3,5-dicarboxyl-ate (PDA) anions and two water mol-ecules with a distorted trigonal-bipyramidal geometry. The tridentate PDA anion is also located on the twofold rotation axis and bridges the Cu(II) cations to form a two-dimensional polymeric layer. O-H⋯O hydrogen bonding between layers links the two-dimensional layers into a three-dimensional supra-molecular framework.

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. One Na(+) cation is coordinated by three carboxyl-ate O atoms and two water mol-ecules and the other is coordinated by five carboxyl-ate O atoms and two water mol-ecules in an irregular 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.

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.
