Catena-Poly[[[diaqua-terbium(III)]-tri-?(2)-isonicotinato-?O:O'] tris(perchlorate) monohydrate].

ABSTRACT: In the title complex, {[Tb(C(6)H(5)NO(2))(3)(H(2)O)(2)](ClO(4))(3)·H(2)O}(n), the Tb(III) ion is coordinated by six O atoms from six isonicotinate (inic) ligands and two water mol-ecules, displaying a bicapped trigonal-prismatic geometry. The inic ligands, which are protonated at the pyridine N atom, link the metal centres, forming a polymeric chain running parallel to the a axis. The chains are further assembled via intra- and inter-molecular O-H?O and N-H?O hydrogen-bonding inter-actions into a three-dimensional supra-molecular network involving the inic ligands, the water mol-ecules and the perchlorate anions. One of the perchlorate ions is disordered over two sites with occupancies of 0.561?(17) and 0.439?(17).

Project description:In the crystal structure of the title complex, [Tb(C(6)H(4)NO(2))(C(2)O(4))(H(2)O)(2)](n), the Tb(III) cation is coordinated by four O atoms from two oxalate ligands, two O atoms from two isonicotinate ligands and two O atoms from water mol-ecules within a distorted square-anti-prismatic coordination. The Tb(III) cation, the isonicotinate anion and the two crystallographically independent water mol-ecules occupy general positions, whereas one of the two crystallographically independent oxalate anions is located on a center of inversion, and the second oxalate anion is located on a twofold rotation axis. The Tb(III) cations are linked by the oxalate and isonicotinate anions into layers, which are connected via inter-molecular hydrogen-bonding and π-π stacking [with centroid-to-centroid distances of 3.509 (2) and 3.343 (3) Å] inter-actions into a three-dimensional network.

catena-Poly[diaqua-tris(?(3)-biphenyl-2,2-dicarboxyl-ato)disamarium(III)].

Project description:The title compound, [Sm(2)(C(14)H(8)O(4))(3)(H(2)O)(2)](n), is composed of one-dimensional chains and is isostructural with previously reported compounds [Wang et al. (2003 ?). Eur. J. Inorg. Chem. pp. 1355-1360]. The asymmetric unit contains two Sm atoms, each of which lies on a crystallographic twofold axis. Both crystallographically independent Sm atoms are coordinated by eight O atoms in a distorted dodeca-hedral arrangement. The polymeric chains run along [001]. Adjacent chains are connected through ?-? inter-actions [centroid-centroid distance = 3.450?(2)?Å], forming a two-dimensional supra-molecular network.

Project description:In the title compound, {[Ag(2)Gd(C(6)H(4)NO(2))(4)(H(2)O)(2)]NO(3)·H(2)O}(n), the Gd(III) ion is coordinated by eight O atoms from six isonicotinate ligands and two water mol-ecules in a distorted square anti-prismatic geometry. Two Ag(I) ions are each bonded to two N atoms from two isonicotinate ligands in a linear or bow-like fashion [N-Ag-N angles = 178.6?(2) and 147.1?(2)°]. These metal ions are connected by the isonicotin-ate ligands into a layer parallel to (010). O-H?O hydrogen bonds donated by the coordinated and uncoordinated water mol-ecules and intra-layer ?-? stacking inter-actions between the pyridine rings [centroid-centroid distances = 3.551?(4) and 3.555?(4)?Å] are observed. The layers inter-act with each other by inter-layer Ag?O(aqua) contacts [2.731?(4)?Å] and ?-? stacking inter-actions between the pyridine rings [centroid-centroid distances = 3.466?(3) and 3.516?(3)?Å], resulting in the formation of a three-dimensional supra-molecular structure.

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.

Project description:The title compound, [CuEu(2)(C(6)H(4)NO(2))(8)(H(2)O)(4)](n), displays a one-dimensional chain structure. The four-coordinate Cu(II) ion (site symmetry ) adopts a trans-CuN(2)O(2) geometry and is bridged by two carboxyl-ate groups from two isonicotinate ligands. The Eu(III) ion adopts a distorted square-anti-prismatic geometry, being coordinated by four O atoms from bridging carboxyl-ate groups of four isonicotinate ligands, two O atoms from chelating carboxyl-ate groups of one isonicotinate ligand and two O atoms from coordinated water mol-ecules; adjacent Eu(III) ions in the chain are related by inversion. The water mol-ecules interact with the ligands via O-H⋯N hydrogen bonds [O⋯O = 2.782 (3)-2.881 (3) Å], which link the chains into a three-dimensional structure.

Poly[[tri-?(3)-hydroxido-tris-(?(4)-pyridine-2,5-dicarboxyl-ato)trineodymium(III)] monohydrate].

Project description:In the title compound, {[Nd(3)(C(7)H(3)NO(4))(3)(OH)(3)]·H(2)O}(n), the Nd(III) atom is eight-coordinated by the three O atoms of three asymmetrically ?(3)-bridging hydroxide groups, by four carboxyl-ate O atoms of four different pyridine-2,5-dicarboxyl-ate (2,5-pydc) ligands, and by the N atom of a 2,5-pydc ligand. Six Nd atoms are connected by six hydroxide groups, forming an [Nd(6)(?(3)-OH)(6)] cluster unit of symmetry -3 and a slightly compressed octa-hedral geometry. Adjacent [Nd(6)(?(3)-OH)(6)] clusters are connected by the 2,5-pydc ligands, via O and N atoms, forming chains along the c axis. The remaining O atoms of the 2,5-pydc ligands link these chains into a three-dimensional framework. A disordered water molecule, located on a threefold rotation axis at the opposite side of the [Nd(6)(?(3)-OH)(6)] cluster and exposed to each of the three Nd atoms, completes the structure.

Poly[[?(2)-acetato-aquadi-?(3)-isonicotinato-dysprosium(III)silver(I)] perchlorate].

Project description:In the title three-dimensional heterometallic complex, {[AgDy(C(6)H(4)NO(2))(2)(C(2)H(3)O(2))(H(2)O)]ClO(4)}(n), the Dy(III) ion is eight-coordinated by four O atoms from four different isonicotinate ligands, three O atoms from two different acetate ligands and one O atom of water mol-ecule. The two-coordinate Ag(I) ion is bonded to two N atoms from two different isonicotinate anions. These metal coordination units are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network. The coordinated water mol-ecules link the carboxyl-ate group and the acetate ligand by O-H?O hydrogen bonding. The perchlorate anion is disordered over two sites with site occupancy factors 0.508?(12) and 0.492?(12) and the methyl group of the acetate ligand is disordered over two positions of equal occupancy.

catena-Poly[2,2',2''-nitrilo-tris-(ethan-aminium) [tri-?-oxido-tris-[dioxido-vanadate(V)]] monohydrate].

Project description:The title compound, {(C6H21N4)[V3O9]·H2O} n , crystallizes as a salt with [trenH3](3+) cations [tren is tris-(2-amino-eth-yl)amine], and one-dimensional anionic {[V(V)O3](-)} n (metavanadate) chains along the c-axis direction. Three crystallographically distinct V(V) sites and one occluded water mol-ecule are present for every [trenH3](3+) cation in the unit cell. The {[V(V)O3](-)} n chains are composed of vertex-sharing [VO4] tetra-hedra and have a repeat unit of six tetra-hedra. Each tetra-hedron in the chain contains two terminal and two ?(2)-bridging oxide ligands. The [trenH3](3+) cations, {[V(V)O3](-)} n anions and occluded water mol-ecules participate in an extensive three-dimensonal hydrogen-bonding network. The three terminal ammonium sites of the [trenH3](3+) cations each form strong N-H?O hydrogen bonds to terminal oxide ligands on the {[V(V)O3](-)} n chain. Each occluded water mol-ecule also donates two O-H?O hydrogen bonds to the terminal oxide ligands.
