Poly[dimethyl-ammonium [aquadi-?(2)-oxalato-dysprosate(III)] trihydrate].

ABSTRACT: The title compound, {(C(2)H(8)N)[Dy(C(2)O(4))(2)(H(2)O)]·3H(2)O}(n), was obtained as an unexpected product under hydro-thermal conditions. The Dy(III) atom is chelated by four oxalate anions, two of which are situated on two different centres of inversion. The distorted tricapped trigonal-prismatic coordination sphere of the Dy(III) atom is completed by a water mol-ecule. The bridging mode of the anions results in the formation of a three-dimensional network with cavities where the ammonium cations and the uncoordinated water mol-ecules reside. The structure is stabilized by numerous N-H?O and O-H?O hydrogen-bonding inter-actions.

Project description:The title complex, {(C(2)H(8)N)[Y(C(2)O(4))(2)(H(2)O)]·3H(2)O}(n), was obtained accidentally under hydro-thermal conditions. The Y(III) atom is chelated by four oxalate ligands and one water mol-ecule resulting in a distorted tricapped trigonal-prismatic geometry. Each oxalate ligand bridges two Y(III) atoms, thus generating a three-dimensional network with cavities in which the ammonium cations and lattice water mol-ecules reside. Various O-H⋯O and N-H⋯O hydrogen-bonding inter-actions stabilize the crystal structure. The title complex is isotypic with the Eu and Dy analogues.

In the packing structure, each oxalate ligand links two Lu(III) and two K atoms, forming a three-dimensional open framework with channels running along [001]. Inter-molecular O-H?O hydrogen bonds occur.

Poly[[tetra-aquadi-?4-fumarato-?2-oxalato-dierbium(III)] tetra-hydrate].

Project description:The title compound, {[Er2(C4H2O4)2(C2O4)(H2O)4]·4H2O} n , was synthesized by the reaction of erbium nitrate hexa-hydrate with fumaric acid and oxalic acid under hydro-thermal conditions. The Er(3+) cation (site symmetry ..2) is eight-coordinated by six O atoms from four fumarate anions (site symmetry ..2) and one bidentate oxalate anion (site symmetry 222), and by two water mol-ecules. The complex exhibits a three-dimensional structure consisting of oxalate pillared Er-fumarate layers with channels occupied by coordinating and lattice water mol-ecules. The three-dimensional structure features by Owater-H?O hydrogen bonds involving both the coordinating and lattice water mol-ecules.

Crystal structure of poly[?6-adipato-di-aquadi-?2-oxalato-didysprosium(III)].

Project description:In the title coordination polymer, [Dy2(C6H8O4)(C2O4)2(H2O)2] n , the asymmetric unit consists of one Dy(3+) cation, one half of an adipate anion, two halves of oxalate anions and one coordinating water mol-ecule. The adipate and oxalate ions are located on centres of inversion. The Dy(3+) cation has a distorted tricapped trigonal-prismatic geometry and is coordinated by nine O atoms, four belonging to three adipate anions, four to two oxalate anions and one from an aqua ligand. The cations are bridged by adipate ligands, generating a two-dimensional network parallel to (010). This network is further extended into three dimensions by coordination of the rigid oxalate ligands and is further consolidated by O-H?O hydrogen bonds. A part of the adipate anion is disordered over two positions in a 0.75:0.25 ratio.

Crystal structure of catena-poly[[aquadi-n-propyl-tin(IV)]-?-oxalato].

Project description:The title compound, [Sn(C3H7)2(H2O)(C2O4)] n , represents the first diorganotin(IV) oxalate hydrate to be structurally characterized. The tin(IV) atom of the one-dimensional coordination polymer is located on a twofold rotation axis and is coordinated by two chelating oxalate ligands with two slightly different Sn-O bond lengths of 2.290?(2) and 2.365?(2)?Å, two symmetry-related n-propyl groups with a Sn-C bond lengths of 2.127?(3)?Å, and a water mol-ecule with a Sn-O bond length of 2.262?(2)?Å. The coordination polyhedron around the Sn(IV) atom is a slightly distorted penta-gonal bipyramid with a nearly linear axis between the trans-oriented n-propyl groups [C-Sn-C = 176.8?(1)°]. The bond angles between the oxygen atoms of the equatorial plane range from 70.48?(6)° to 76.12?(8)°. A one-dimensional coordination polymer results from the less asymmetric bilateral coordination of the centrosymmetric oxalate anion, inter-nally reflected by two slightly different C-O bond lengths of 1.248?(3) and 1.254?(3)?Å. The chains of the polymer propagate parallel to [001] and are held together by hydrogen bonds between water mol-ecules and oxalate anions of neighboring chains, leading to a two-dimensional network parallel to (100).

Poly[diethyl-enetriammonium [aquadi-?(2)-sulfato-sulfatocerium(III)]].

Project description:A new organically templated open-framework cerium sulfate, {(C(4)H(16)N(3))[Ce(SO(4))(3)(H(2)O)]}(n), was hydro-thermally synthesized. The Ce(III) cation is nine-coordinated by nine O atoms, including one water mol-ecule. Two of the SO(4) groups afford one monodentate and bidentate linkages as the bridge to connect adjacent Ce(III) cations, while the third SO(4) group attaches the Ce(III) cation in a bidentate mode. The crystal structure consists of layers composed of eight-membered-ring networks formed by four CeO(9) polyhedra and four SO(4) tetra-hedra. The triply protonated diethyl-enetriamine cations are located between adjacent layers and connect the layers via hydrogen bonds.

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.
