Poly[[?(2)-acetato-aquadi-?(3)-isonicotinato-erbium(III)silver(I)] perchlorate].

ABSTRACT: In the title three-dimensional heterometallic complex, {[AgEr(C(6)H(4)NO(2))(2)(C(2)H(3)O(2))(H(2)O)]ClO(4)}(n), the eight-coordin-ate Er(III) ion adopts a distorted bicapped trigonal-prismatic geometry, being coordinated by four O atoms from four different isonicotinate ligands, three O atoms from two different acetate ligands and one O atom of the water mol-ecule. The two-coordinate Ag(I) ion is surrounded by two N atoms from two different isonicotinate anions in a slightly bent configuration. These building blocks are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network. Ths structure is consolidated by O-H?O hydrogen bonding between the coordinated water mol-ecule and a carboxyl-ate group of the acetate ligand. The perchlorate anion is disordered over two sites with site-occupancy factors of 0.526?(13) and 0.474?(13), while the methyl group of the acetate ligand is equally disordered over two sites.

Poly[[tetra-kis-(μ(2)-pyrazine N,N'-dioxide-κO:O')erbium(III)] tris-(perchlorate)].

Project description:The title three-dimensional coordination network, {[Er(C(4)H(4)N(2)O(2))(4)](ClO(4))(3)}(n), is isostructural to that of other lanthanides. The Er(+3 )cation lies on a fourfold roto-inversion axis. It is coordinated in a distorted square-anti-prismatic fashion by eight O atoms from bridging pyrazine N,N'-dioxide ligands. There are two unique pyrazine N,N'-dioxide ligands. One ring is located around an inversion center, and there is a a twofold rotation axis at the center of the other ring. There are also two unique perchlorate anions. One is centered on a twofold rotation axis and the other on a fourfold roto-inversion axis. The perchlorate anions are located in channels that run perpendicular to (001) and (110) and inter-act with the coordination network through C-H⋯O hydrogen bonds.

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

Project description: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.
