Catena-Poly[[[triaqua-copper(II)]-μ(2)-pyrazine-2,3-dicarboxyl-ato] monohydrate].

ABSTRACT: 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.

Project description:In the title compound, {[Cu(C(7)H(3)NO(4))(H(2)O)(3)]·H(2)O}(n), the Cu(II) ion is bonded to three water mol-ecules, one N,O-bidentate pyridine-2,3-dicarboxyl-ate dianion and one O-bonded symmetry-generated dianion, resulting in a distorted CuNO(5) octa-hedral geometry. The bridging ligand results in an infinite chain. A network of O-H⋯O hydrogen bonds helps to establish the crystal structure.

Project description:The title compound, {[Cu(C(12)H(6)N(2)O(4))(H(2)O)(3)]·H(2)O}(n), was synthesized under hydro-thermal conditions. The Cu(2+) ion is six-coordinated by three water O atoms, and two N atoms and one O atom of the 2,2'-bipyridine-3,3'-dicarboxyl-ate bridging ligand in a sligthly distorted octa-hedral environment. The 2,2-bipyridine-3,3'-dicarboxyl-ate bridges link the Cu(2+) ions into chains along the b-axis direction. These chains are further linked by O-H⋯O hydrogen bonds involving the water solvent mol-ecules, forming a three-dimensional framework.

Project description:The crystal structure of the title compound, {[Fe(C(6)H(2)N(2)O(4))(H(2)O)(2)]·2H(2)O}(n), was synthesized by a diffusion method. It has a one-dimensional polymeric chain structure and the chains are further connected into a three-dimensional structure by hydrogen bonds. The Fe(II) ion has a distorted octa-hedral coordination environment, with two N and two O atoms from the pyrazine-2,3-dicarboxyl-ate ligands in the equatorial plane and with two water mol-ecules in axial positions. The Fe atom lies on a crystallographic centre of symmetry and a twofold rotation axis passes through the pyrazine ring.

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.

catena-Poly[[[triaqua-cobalt(II)]-μ-10-methyl-phenothia-zine-3,7-dicarboxyl-ato] monohydrate].

Project description:The polymeric title compound, {[Co(C(15)H(9)NO(4)S)(H(2)O)(3)]·H(2)O}(n), consists of chains along [001] made up from Co(2+) ions bridged by 10-methyl-phenothia-zine-3,7-dicarboxyl-ate anions. The Co(2+) ion, coordinated by three O atoms from two different carboxyl-ate groups and three water mol-ecules, displays a distorted octa-hedral environment. In the crystal, π-π inter-chain inter-actions, with centroid-centroid distances of 3.656 (2) and 3.669 (2) Å between the benzene rings of the ligands, assemble the chains into sheets parallel to (100). O-H⋯O hydrogen-bonding inter-actions between the coordinating water mol-ecules and carboxyl-ate O atoms link the sheets into a three-dimensional network.

catena-Poly[[[diaqua-copper(II)]-μ-quinoline-2,3-dicarboxyl-ato-κ(3)N,O(2):O(3)] monohydrate].

Project description:In the title compound, {[Cu(C(11)H(5)NO(4))(H(2)O)(2)]·H(2)O}(n), the Cu(II) ion is five-coordinated by two O atoms and one N atom of two symmetry-related quinoline-2,3-dicarboxyl-ate ligands, and two water mol-ecules. The water mol-ecules occupy basal and apical positions of the square-pyramidal coordination polyhedron. Each quinoline-2,3-dicarboxyl-ate dianion bridges two adjacent Cu(II) ions, forming a polymeric chain along [010]. The chains are further connected via O-H⋯O hydrogen-bonding inter-actions and quinoline ring π-π inter-actions [centroid-centroid distance = 3.725 (4) Å], generating a three-dimensional structure. Lattice water mol-ecules participate in the crystal structure via O-H⋯O hydrogen bonds.

Poly[[(N,N-dimethyl-formamide-κO)(μ(3)-pyrazine-2,3-dicarboxyl-ato-κN,O:O:O)copper(II)] monohydrate].

Project description:In the title compound, {[Cu(C(6)H(2)N(2)O(4))(C(3)H(7)NO)]·H(2)O}(n), the Cu(II) atom is coordinated by an N,O-bidentate pyrazine-2,3-dicarboxyl-ate (pzdc) dianion, two O atoms from two other pzdc anions and one O atom from the dimethlyformamide ligand, forming a distorted square-pyramidal CuNO(4) geometry. The polymeric character of the structure is established by the formation of layers parallel to (100) via bridging pzdc ligands. O-H⋯O hydrogen bonding between water mol-ecules and uncoordinated carboxyl-ate O atoms leads to additional stabilization of the structure.

Project description:The title complex, [Cd(C(6)H(2)N(2)O(4))(H(2)O)(3)](n), is a new monoclinic polymorph. The ortho-rhom-bic form has previously been reported [Ma et al. (2006 ▶). Acta Cryst. E62, m2528-m2529]. The Cd-N and Cd-O bond lengths range from 2.265 (3) to 2.333 (3) Å; a weak Cd-O inter-action is also present, the inter-atomic distance being 2.658 (4) Å. The Cd(II) ions, which have a distorted penta-gonal-bipyramidal geometry, are bridged by pyrazine-2,3-dicarboxyl-ato ligands, forming a zigzag chain structure. The chains are connected by O-H⋯O hydrogen bonds into a three-dimensional framework.

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.
