Poly[[di-?(3)-nicotinato-?(3)-oxalato-samarium(III)silver(I)] dihydrate].

ABSTRACT: In the title three-dimensional heterometallic complex, {[AgSm(C(6)H(4)NO(2))(2)(C(2)O(4))]·2H(2)O}(n), the Sm(III) ion is eight-coordinated by four O atoms from four different nicotinate ligands and four O atoms from two different oxalate ligands. The three-coordinate Ag(I) ion is bonded to two N atoms from two different nicotinate anions and one O atom from an oxalate anion. These metal coordination units are connected by bridging nicotinate and oxalate ligands, generating a three-dimensional network. The uncoordinated water mol-ecules link the carboxyl-ate groups via O-H?O hydrogen bonding. The crystal structure is further stabilized by hydrogen bonds between the water mol-ecules.

Project description:The asymmetric unit of the title compound, {[AgNd(C(6)H(4)NO(2))(2)(C(2)O(4))]·2H(2)O}(n), contains one Nd(III) atom, one Ag(I) atom, one oxalate ligand, two nicotinate ligands and two uncoordinated water mol-ecules. The Nd(III) atom is eight-coordinated in a distorted square-anti-prismatic coordination geometry by four O atoms from two oxalate ligands and four O atoms from four nicotinate ligands. The Ag(I) atom has a T-shaped configuration, defined by two N atoms from two nicotinate ligands and one O atom from one oxalate ligand. The nicotinate and oxalate ligands link the Nd and Ag atoms into a three-dimensional coordination framework. O-H?O and O-H?N hydrogen bonds donated by water mol-ecules are observed in the crystal.

Poly[[tetra-aqua-di-?(4)-oxalato-?(2)-oxalato-dineo-dymium(III)] dihydrate].

Project description:The title compound, {[Nd(2)(C(2)O(4))(3)(H(2)O)(4)]·2H(2)O}(n), was synthesized hydro-thermally in the presence of bis-(carb-oxy-ethyl-germanium) sesquioxide. It is isostructural with the corresponding Pr compound [Yang et al. (2009). Acta Cryst. E65, m1152-m1153]. The Nd(3+) cation is nine-coordinated and its coordination polyhedron can be described as a distorted tricapped trigonal prism. Two Nd(3+) ions are connected by two O atoms from two oxalate ions to give a dinuclear Nd(2) unit. The unit is further linked to four others via four oxalate ions yielding a layerparallel to (0-11). The linkages between the layers by neighbouring oxalate anions lead to a three-dimensional framework with channels along the c axis. The coordinating and free water mol-ecules are located in the channels and make contact with each other and the host framework by weak O-H?O hydrogen bonds.

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.

Project description:In the title homochiral three-dimensional heterometallic complex, [AgSm(C(6)H(4)NO(2))(3)(C(2)H(3)O(2))](n), the eight-coordinate Sm(III) ion displays a bicapped trigonal-prismatic geometry, being coordinated by two O atoms from one acetate ligand, four O atoms from four bridging isonicotinate ligands and two O atoms from two terminal isonicotinate ligands. The four-coordinate Ag(I) ion adopts a tetra-hedral geometry, being bonded to two N atoms from two bridging isonicotinate ligands and two O atoms from two acetate ligands. These metal coordination units are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network.

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.

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 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:In the title compound, {[AgSm(C(6)H(4)NO(2))(2)(C(2)O(4))]·H(2)O}(n), the asymmetric unit contains one Sm(III) ion, one Ag(I) ion, two unique isonicotinate (ina) ligands, two half oxalate (ox) ligands (one on an inversion centre, the other on a twofold axis) and one uncoordinated water mol-ecule.

The Ag(I) ion is three-coordinated in a T-shaped geometry involving two ina N-donor atoms [Ag-N = 2.181?(6) and 2.185?(5)?Å] and a bridging oxalate O-donor atom [Ag-O = 2.620?(4)?Å]. The three-dimensional heterometallic Sm-Ag coordination polymer, having a unique (3,4,6)-connected five-nodal net topology, is constructed from two-dimensional samarium-oxalate layers and pillared Ag(ina)(2) subunits. Inter-molecular water-carboxyl-ate O-H?O hydrogen-bonding inter-actions are also present.

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.

The anions self-assemble into polymeric chains via W-S-Ag bridges having a [AgS(4)W] repeat unit; the W-Ag-W and Ag-W-Ag angles are 161.657?(17) and 153.978?(9)°, respectively. The title complex is isostructural with the Y, Yb, Eu, Nd, La and Dy isomorphs.
