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

ABSTRACT: 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.

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.

Project description:In the title complex, {[Pr(C(2)O(4))(1.5)(H(2)O)(2)]·H(2)O}(n), the Pr(III) ion, which lies on a crystallographic inversion centre, is coordinated by seven O atoms from four oxalate ligands and two O atoms from two water ligands; further Pr-O coordination from tetra-dentate oxalate ligands forms a three-dimensional structure. The compound crystallized as a monohydrate, the water mol-ecule occupying space in small voids and being secured by O-H⋯O hydrogen bonding as an acceptor from ligand water H atoms and as a donor to oxalate O-acceptor sites.

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.

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[diimidazole-μ(4)-oxalato-μ(2)-oxalato-dicopper(II)].

Project description:The title compound, [Cu(2)(C(2)O(4))(2)(C(3)H(4)N(2))(2)](n), was obtained as an unexpected product under hydro-thermal conditions. The Cu(II) atom is in a Jahn-Teller-distorted octa-hedral environment formed by one imidazole N atom and five O atoms from three oxalate anions. The two independent oxalate anions are situated on centres of inversion and coordinate to the Cu(II) atom in two different modes, viz. bidentate and monodentate. The bidentate anions bridge two Cu(II) atoms, whereas the monodentate anions bridge four Cu(II) atoms, leading to a layered arrangement parallel to (100). These layers are further linked into a final three-dimensional network structure via inter-molecular N-H⋯O hydrogen bonds. The title compound is isotypic with the Zn analogue.
