Poly[diaqua-?(2)-oxalato-di-?(4)-terephthalato-diytterbium(III)].

ABSTRACT: The crystal structure of the title complex, [Yb(2)(C(8)H(4)O(4))(2)(C(2)O(4))(H(2)O)(2)](n), features an extended three-dimensional framework made up of Yb(3+) ions coordinated by terephthalate ligands, oxalate ligands and water mol-ecules. The Yb(3+) ion has a distorted square-anti-prismatic coordination formed by one aqua ligand, two O atoms from an oxalate ligand and five O atoms belonging to four terephthalate anions. Two symmetry-independent terephthalate anions, as well as the oxalate anion, occupy special positions on inversion centers. The water molecule participates in O-H?O hydrogen bonding with both terephthalate anions.

Project description:In the title compound, [Lu(2)(C(8)H(4)O(4))(2)(C(2)O(4))(H(2)O)(2)](n), the Lu(3+) cations are each coordinated by eight O atoms of four terephthalate anions, one oxalate anion and one aqua ligand to complete a distorted square-anti-prismatic geometry. They are bridged by the terephthalate ligands, generating a three-dimensional framework, which is further stabilized by the oxalate ligands. The terephthalate ions and oxalate ions are all located on centers of inversion.

Project description:In the title compound, [Y(2)(C(4)H(4)O(4))(2)(C(2)O(4))(H(2)O)(2)](n), the flexible succinate anion assumes a gauche conformation and bridges the eight-coordinated Y atoms, generating two-dimensional layers parallel to (010). The coordination polymer layers are linked into a three-dimensional framework by the rigid oxalate ligands. The oxalate ions are located on a center of inversion.

Project description:In the title two-dimensional coordination polymer, [Yb(2)(C(8)H(4)O(4))(3)(H(2)O)(6)](n), the unique Yb(III) ion is eight-coordinated in a distorted dodeca-hedral coordination geometry by three water O atoms and five O atoms from carboxyl-ate groups belonging to four different terephthalate ligands. One of the terephthalate ligands is located around an inversion center. The coordination polymers are parallel to (121) and are connected by O-H?O hydrogen bonds into a three-dimensional framework.

Poly[diaqua-μ(2)-isonicotinato-μ(2)-oxalato-terbium(III)].

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.

Poly[diaqua-μ(2)-isonicotinato-μ(2)-oxalato-terbium(III)].

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) ion is coordinated by two O atoms from two isonicotinate (inic) anions, four O atoms of two oxalate anions, and two water mol-ecules, displaying a distorted square-antiprismatic geometry. The Tb(III) ion, the inic anion and the water mol-ecules occupy general positions. One of the two crystallographically independent oxalate anions is located on a center of inversion, whereas the second is located on the twofold rotation axis. The carboxyl-ate groups of the inic and oxalate anions link the terbium metal centres into layers. These layers are connected by O-H⋯O and N-H⋯O hydrogen bonding into a three-dimensional network.

Poly[diaqua-μ(4)-oxalato-di-μ(6)-phosphato-tetra-cobalt(II)].

Project description:In the structure of the title compound, [Co(4)(C(2)O(4))(PO(4))(2)(H(2)O)(2)](n), there are layers composed of the phosphate anions and two independent Co(II) cations. These layers are parallel to (001) and are bridged by the oxalate anions that are situated in special positions on centres of symmetry. One independent Co atom has an octa-hedral coordination, while the second independent Co atom is coordinated in a trigonal-bipyramidal coordination that includes the water mol-ecule. The crystal packing is stabilized by O-H⋯O hydrogen bonds between the coordinated water mol-ecules and oxalate O atoms.

The carboxyl-ate groups of pyrazine-2-carboxyl-ate and oxalate ligands link the lanthanum metal centres, forming layers parallel to (10). The layers are further connected by inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions, forming a three-dimensional supra-molecular network.

Poly[hemi(ethyl-enediammonium) [di-μ-oxalato-indium(III)] dihydrate].

Project description:In title compound, {(C(2)H(10)N(2))(0.5)[In(C(2)O(4))(2)]·2H(2)O}(n), the unique In(III) ion is coordinated by eight O atoms from four oxalate ligands in a distorted square-anti-prismatic environment. The doubly bis-chelating oxalate ligands act as bridging ligands connecting symmetry-related In(III) ions and forming a three-dimensional open framework structure. Ethyl-enediammonium cations and water mol-ecules occupy the voids within the structure. The unique ethyl-enediammonium cation and one water mol-ecule both lie on a twofold rotation axis. One of the other two water mol-ecules residing on general crystallographic sites was refined as disordered with half occupancy. In the crystal structure, cations and water mol-ecules are linked to the anionic framework via inter-molecular O-H⋯O and N-H⋯O hydrogen bonds.

Poly[disodium [diaqua-tri-μ(2)-oxalato-dimagnesium(II)]].

Project description:The title compound, {Na(2)[Mg(2)(C(2)O(4))(3)(H(2)O)(2)]}(n), is isotypic with its Co analogue. There are two crystallographically independent oxalate groups in the asymmetric unit, one lying on an inversion center and the other on a general position. Mg(2+) ions are ligated by H(2)O mol-ecules and bridged by tri- and tetra-dentate oxalate ligands, forming ladder-like double chains that are held together via O-H⋯O hydrogen bonds, with Na(+) cations located between the chains to balance the charge.

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

Project description:The title compound, {[Tm(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 Tb(III) compound [Li et al. (2009 ▶). Acta Cryst. E65, m410]. All interatomic distances and angles and the hydrogen-bond geometries are very similar for the two structures. The refined Flack parameter of 0.49 (2) suggests inversion twinning.
