Catena-Poly[[[aqua-(pyridine-4-carboxyl-ato-?N)silver(I)]-?-hexa-methyl-ene-tetra-amine-?N:N'] dihydrate].

ABSTRACT: In the title compound, {[Ag(C(6)H(4)NO(2))(C(6)H(12)N(4))(H(2)O)]·2H(2)O}(n), the Ag(I) atom shows a distorted triangular pyramidal geometry,, formed by two N atoms from two hexa-methyl-ene-tetra-amine (hmt) ligands and one N atom from a pyridine-4-carboxyl-ate (4-pdc) ligand and one water mol-ecule. The hmt ligands bridge the Ag atoms, forming a chain along [001]. The carboxyl-ate group of the 4-pdc ligand is uncoordinated. O-H?O hydrogen bonds between the water mol-ecules and carboxyl-ate groups stabilize the structure.

Project description:The asymmetric unit of the title compound, {[Zn(2)(C(10)H(2)O(8))(H(2)O)(6)]·2H(2)O}(n), contains two distinct Zn atoms joined by a bridging water molecule and two bridging carboxyl-ate groups belonging to distinct halves of benzene-1,2,4,5-tetra-carboxyl-ate (tbec) tetra-anionic ligands, both lying on crystallographic inversion centres. The structure of this new isopolymorphic one-dimensional coordination polymer features asymmetric bimetallic octa-hedral knots. O-H?O hydrogen bonds between water molecules and carboxylate O atoms help to consolidate the crystal packing.

Tetra-aqua-hexa-kis(?(2)-quinoline-4-carboxyl-ato)diyttrium(III) dihydrate.

Project description:In the title centrosymmetric binuclear complex, [Y(2)(C(10)H(6)NO(2))(6)(H(2)O)(4)]·2H(2)O, each Y(III) atom is nine-coordin-ated by nine O atoms from five ligands and two water mol-ecules in a slightly distorted monocapped square-anti-prismatic coordination environment. The Y(III) atoms are separated by a distance of 4.0363?(9)?Å. The ligands coordinate in three different modes: chelating, bridging and a mixed chelating bridging mode. In the crystal structure, the binuclear complexes are linked by O-H?O and O-H?N hydrogen bonds, forming a three-dimensional network.

Project description:In the polymeric complex of the title compound, {[AgNi(C(5)H(3)N(2)O(2))(2)(H(2)O)(2)]NO(3)·2H(2)O}(n), the Ag(I) ion displays an angular coordination geometry with two N atoms from pyrazine-2-carboxyl-ate ligands, and the Ni(II) ion is hexa-coordinated by two O atoms from two water mol-ecules, two O and two N atoms from pyrazine-2-carboxyl-ate ligands in a distorted octa-hedral geometry. In the crystal, the Ag(I) and Ni(II) ions lie on a mirror plane and an inversion centre, respectively. The complex chains, the nitrate ions and the uncoordinated water mol-ecules are linked together through O-H?O hydrogen bonds and weak Ag?O inter-actions [2.619?(17)-2.749?(17)?Å] into a three-dimensional network.

Poly[[hexa-?-aqua-diaqua-bis-(??-dihydrogen benzene-1,2,4,5-tetra-carboxyl-ato)magnesiumdisodium] dihydrate].

Project description:The asymmetric unit of the title compound, {[MgNa?(C??H?O?)?(H?O)?]·2H?O}(n), contains one octa-hedrally coordin-ated Mg(II) atom (site symmetry 2/m), one octahedrally coordinated Na(I) atom (site symmetry 2) and one half of the dihydrogen benzene-1,2,4,5-tetra-carboxyl-ate (btec) ligand, the second half of the ligand being generated by a twofold rotation axis. The basic framework of the title compound features infinite (-Na-Na-Mg-)(n) chains along [10-1] with the metal cations bridged by the coordinating water molecules. The chains are isolated from each other by ??-bridging btec ligands, which form inter-molecular O-H?O hydrogen bonds to uncoordinated water mol-ecules and the coordinated water mol-ecules of a neighbouring chain. In each btec ligand, there are also intramolecular O-H?O hydrogen bonds.

A novel double-chain silver(I) coordination polymer: catena-poly[[[?-aqua-aqua-disilver(I)]-bis-(?(3)-5-methyl-pyrazine-2-carboxyl-ato)] dihydrate].

Project description:In the title silver(I) coordination polymer, {[Ag(2)(C(6)H(5)N(2)O(2))(2)(H(2)O)(2)]·2H(2)O}(n), the [Ag(2)(?(2)-H(2)O)(H(2)O)] cores are extended by anti-parallel 5-methyl-pyrazine-2-carboxyl-ate (L) ligands, forming a novel double-chain structure. Both Ag(+) cations show a distorted square-pyramidal coordination. Ag1 is bonded to two water molecules, one L N atom, one N atom and one carboxylate O atom from a neighbouring L, whereas Ag2 is surrounded by two L N atoms, two L carboxylate O atoms and one bridging water molecule. O-H?O hydrogen-bonding inter-actions involving water clusters and carboxyl-ate O atoms link the mol-ecules into a three-dimensional supra-molecular architecture, which is further consolidated by weak C-H?O inter-actions and ?-? stacking inter-actions [centroid-centroid distance 3.643?(5)?Å].

Tetra-aqua-bis(3-fluoro-pyridine-4-carboxyl-ato-?N)zinc(II) dihydrate.

Project description:In the title compound, [Zn(C(6)H(3)FNO(2))(2)(H(2)O)(4)]·2H(2)O, the Zn(II) atom is octa-hedrally coordinated in a ZnO(4)N(2) environment by two 3-fluoro-pyridine-4-carboxyl-ate (3-fpy4-cbx) ligands and four water mol-ecules. The [Zn(3-fpy4-cbx)(2)(H(2)O)(4)] mol-ecules form a three-dimensional network through strong O-H?O and weak O-H?F hydrogen bonds between 3-fpy4-cbx and water mol-ecules. The crystal used for data collection was a twin, with the twin law corresponding to a 180° rotation about the real-space [001] axis. The major twin fraction refined to 0.795?(1).

catena-Poly[bis-(4-amino-pyridinium) [[tetra-aqua-nickel(II)]-?-benzene-1,2,4,5-tetra-carboxyl-ato] dihydrate].

Project description:The asymmetric unit of the title compound, {(C(5)H(7)N(2))(2)[Ni(C(10)H(2)O(8))(H(2)O)(4)]·2H(2)O}(n), contains an Ni(II) atom, two water mol-ecules of coordination, one half of a benzene-1,2,4,5-tetra-carboxyl-ate (btec) anionic ligand, one 4-amino-pyridinium cation (papy) and an uncoordinated water mol-ecule. The metal center lies on an inversion center and adopts an octa-hedral geometry with the carboxyl-ate groups tilted out of the mean plane formed by the btec. In the crystal, mol-ecules are linked into one-dimensional coordination polymers running along the ac diagonal. The crystal structure is consolidated by N-H?O and O-H?O hydrogen bonds.

Guanidinium hexa-aqua-zinc(II) bis[tris-(3-carb-oxy-pyridine-2-carboxyl-ato)zincate].

Project description:In the title mol-ecular salt, (CH(6)N(3))(1.30)[Zn(H(2)O)(6)](0.35)[Zn(C(7)H(4)NO(4))(3)](2), the Zn(II) atom (site symmetry 3) in the anion is coordinated by three N,O-bidentate 3-carb-oxy-pyridine-2-carboxyl-ate monoanions to generate a fac-ZnN(3)O(3) octa-hedral coordination geometry. The guanidinium cation (the C atom has site symmetry 3) and the octa-hedral hexa-aqua-zinc(II) dication (the Zn(2+) cation has site symmetry -3) are occupationally disordered in a 1.30:0.35 ratio. In the crystal, the components are linked by O-H?O and N-H?O hydrogen bonds to generate infinite (001) sheets. Weak aromatic ?-? stacking [centroid-centroid distance = 3.797?(8)?Å] is also observed in the crystal.

catena-Poly[[[diaqua-terbium(III)]-μ-6-carboxy-nicotinato-μ-pyridine-2,5-di-carboxyl-ato] dihydrate].

Project description:The title compound, {[Tb(C(7)H(3)NO(4))(C(7)H(4)NO(4))(H(2)O)(2)]·2H(2)O}(n), is isotypic with the analogous Tm(III) compound [Li, Zhang, Wang & Bai (2009). Acta Cryst. E65, m411]. The Tb(III) atom is octa-coordinated by two water mol-ecules and by four carboxyl-ate O atoms and two pyridyl N atoms from two pyridine-2,5-dicarboxyl-ate (2,5-pydc) and two 6-carboxy-nicotinate (2,5-Hpydc) ligands. The 2,5-pydc and 2,5-Hpydc ligands bridge Tb(III) atoms, generating helical coordination polymers along [001]. An extensive network of O-H⋯O hydrogen bonds is formed between the coordination polymers and the uncoordinated water mol-ecules. The refined Flack parameter of 0.54 (2) suggests inversion twinning.
