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

ABSTRACT: 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: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.

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. Inter-molecular O-H⋯O hydrogen bonds help to stabilize the crystal structure.

Project description: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.

A one-dimensional inorganic-organic hybrid compound: catena-poly[ethyl-enediammonium [indate(III)-di-μ-hydrogenphosphato(V)-μ-hydroxido] monohydrate].

Project description:The title compound, (C(2)H(10)N(2))[In(HPO(4))(2)(OH)]·H(2)O, was synthesized under hydro-thermal conditions. The structure of this hybrid compound consists of isolated inorganic chains with composition (∞)[In(HPO(4))(4/2)(OH)(2/2)] running along [010]. The coordination of the In(III) atom is distorted octa-hedral. The ethyl-enediammonium cation and the disordered water mol-ecule (site-occupation factors = 0.7:0.3) ensure the cohesion of the structure via N-H⋯O and O-H⋯O hydrogen bonds.

Project description: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.
