Poly[triaqua-?(4)-pyridine-3,5-dicarboxyl-ato-barium(II)].

ABSTRACT: The reaction of the proton-transfer compound (pdaH(2))(py-3,5-dc)·H(2)O (pda = propane-1,3-diamine and py-3,5-dcH(2) = pyridine-3,5-dicarboxylic acid) with Ba(NO(3))(2) leads to the formation of the title polymeric compound, [Ba(C(7)H(3)NO(4))(H(2)O)(3)](n). The Ba(II) atom is nine-coordinated by six carboxyl-ate O atoms from the (py-3,5-dc)(2-) ligands, and three O atoms from the coordinated water mol-ecules. The coordination polyhedron around the Ba(II) atom is best described as tricapped trigonal-prismatic. In the crystal structure, inter-molecular inter-actions, such as X-H?O hydrogen bonds (X = O and C) and ?-? stacking [centroid-centroid distances between pyridine rings of 3.6191?(13) and 3.6192?(13)?Å] play an important role in stabilizing the supramolecular structure.

Project description:The asymmetric unit of the title compound, [Ce(2)(C(7)H(3)NO(4))(3)(H(2)O)(3)](n), contains two Ce(III) cations, three pyridine-3,5-dicarboxyl-ate (pyd) anions and three coordinated water mol-ecules. One Ce(III) cation is coordinated by seven carboxyl-ate O atoms from six pyd anions and two water mol-ecules in a square-face-capped square-anti-prismatic geometry. Another Ce(III) cation is coordinated by seven O atoms from six pdy anions and one water mol-ecule in a bicapped trigonal-prismatic geometry. The pdy anions bridge the Ce(III) cations, forming the three-dimensional polymeric structure. The crystal structure contains extensive O-H⋯O, O-H⋯N and weak C-H⋯O hydrogen bonds. π-π stacking is present in the crystal structure, the shortest centroid-centroid distance between parallel pyridine rings being 3.509 (4) Å.

Project description:In the title compound, [Zn(C(4)HN(3)O(4))(H(2)O)(3)](n), each Zn(II) atom adopts a distorted octa-hedral coordination geometry, being surrounded by one chelating and one monodentate 1H-1,2,4-triazole-3,5-dicarboxyl-ate ligand and three water mol-ecules. Adjacent Zn(II) cations are linked by a 1H-1,2,4-triazole-3,5-dicarboxyl-ate ligand in a μ(2),κ(3) fashion to form a chain running along the c axis. The crystal packing is stabilized by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds.

Poly[tetra-aqua-μ(3)-pyridine-3,5-dicarboxyl-ato-strontium(II)].

Project description:The reaction of strontium(II) nitrate with the proton-transfer compound (pdaH(2))(py-3,5-dc)·H(2)O (where pda = propane-1,3-diamine and py-3,5-dcH(2) = pyridine-3,5-dicarboxylic acid) leads to the formation of the title polymeric compound, [Sr(C(7)H(3)NO(4))(H(2)O)(4)](n). The propane-1,3-diaminium cation is not incorporated in this crystal structure. The Sr(II) atom lies on an inversion centre and is eight-coordinated by four O atoms from three py-3,5-dc ligands and four O atoms from four coordinated water mol-ecules. The coordination polyhedron of the Sr(II) atom is a distorted dodeca-hedron. These binuclear units are connected via the carboxyl-ate O atoms to build a one-dimensional polymeric chain. In the crystal structure, non-covalant inter-actions consisting of hydrogen bonds (X-H⋯O, with X = O and C) and π-π stacking inter-actions [3.4604 (19) Å] connect the various components to form a supra-molecular structure.

catena-Poly[[triaqua-cadmium(II)]-μ-pyridine-2,3-dicarboxyl-ato-κN,O:O].

Project description:The title polymeric compound, [Cd(C(7)H(3)NO(4))(H(2)O)(3)](n) or [Cd(py-2,3-dc)(H(2)O)(3)](n), where py-2,3-dcH(2) is pyridine-2,3-dicarboxylic acid, was obtained by the reaction of cadmium(II) nitrate hexa-hydrate with (pipzH(2))(py-2,3-dc) as a proton-transfer compound in aqueous solution (pipz is piperazine). The mol-ecular structure shows that only the anionic fragment of the starting proton-transfer compound is present in the complex, while the (pipzH(2))(2+) dication has been lost. Each (py-2,3-dc)(2-) ligand bridges two Cd(II) atoms in two different coordination modes, i.e. one end acts as a monodentate and the other end as a bidentate ligand. The three remaining coordination sites on the metal center are occupied by water mol-ecules. The geometric arrangement of the six donor atoms around the Cd(II) atom is distorted octa-hedral. In the crystal structure, O-H⋯O and C-H⋯O hydrogen bonds play an important role in stabilizing the supra-molecular structure.

The carboxyl-ate groups of the pda anions bridge the Pb ions, forming a two-dimensional coordination polymer parallel to (100). Weak inter-molecular C-H⋯O hydrogen boning is present in the crystal structure.

catena-Poly[[[diaqua-iron(II)]-μ-pyridine-2,5-dicarboxyl-ato-[tetra-aqua-iron(II)]-μ-pyridine-2,5-dicarboxyl-ato] tetra-hydrate].

Project description:In the crystal structure of the title compound, {[Fe(2)(C(7)H(3)NO(4))(2)(H(2)O)(6)]·4H(2)O}(n), there are two types of coordination for the Fe(II) atoms. One Fe(II) atom is in a distorted octa-hedral N(2)O(4) environment, with two chelating rings from the pyridine-dicarboxyl-ate ligands and two O atoms from the water mol-ecules, while the other is in a distorted octa-hedral O(6) environment with two O atoms from the pyridine-dicarboxyl-ate ligands and four O atoms from the water mol-ecules. Both Fe(II) atoms lie on crystallographic centers of symmetry. The complex possesses an infinite chain structure running along the [101] direction. These chains are inter-connected by the uncoordinated water mol-ecules through O-H⋯O hydrogen bonds.

Project description:The Cu atom in the title complex, {[Cu(C(6)H(2)N(2)O(4))(H(2)O)(3)]·H(2)O}(n) or {[Cu(L)(H(2)O)(3)]·H(2)O}(n) (L is pyrazine-2,3-dicarbox-yl-ate), displays octa-hedral coordination formed by the ligand L and three coordinated water mol-ecules. The ligand L is tridentate, with one N atom of the pyrazine ring and one O atom of one carboxyl-ate group forming a chelate ring, whereas one O atom from the second carboxyl-ate group is coordinated to another Cu atom. The ligand L links mol-ecules to form an infinite chain parallel to the [101] direction. The chains are further linked through O-H⋯O and O-H⋯N hydrogen bonds involving the water mol-ecules to build up a three-dimensional network.
