Poly[tris-(?(3)-5-amino-isophthalato)diaqua-dicerium(III)].

ABSTRACT: In the title complex, [Ce(2)(C(8)H(5)NO(4))(3)(H(2)O)(2)](n), each Ce ion is in nine-coordinated environment. Eight O atoms from six ligands participate in coordination, in addition to one O atom from a water mol-ecule. Both carboxyl-ate groups from the ligands chelate the Ce atoms, forming two four-membered rings. The 5-amino-isophthalate ligands also bridge the Ce centers, forming a two-dimensional network, and O-H?O and N-H?O hydrogen bonds complete the structure.

Poly[diaqua-tris-(μ(4)-1,3-phenyl-ene-diacetato)-dicerium(III)].

Project description:In the title coordination polymer, [Ce(2)(C(10)H(8)O(4))(3)(H(2)O)(2)](n), each Ce(III) atom is nine-coordinated by eight O atoms from six different 1,3-phenyl-enediacetate (pda) bivalent anions and one O atom from a coordinated water mol-ecule, forming a distorted tricapped trigonal-prismatic coordination geometry. Eight Ce(III) ions and twelve pda ligands form a large [Ce(8)(pda)(12)] ring, and four Ce(III) ions and six pda ligands form a small [Ce(4)(pda)(6)] ring. The rings are further connected by the coordination inter-actions of pda ligands and Ce(III), generating a three-dimensional supra-molecular framework.

Poly[diaqua-tris(?(4)-isophthalato)dilanthanum(III)].

Project description:In the title coordination polymer, [La(2)(C(8)H(4)O(4))(3)(H(2)O)(2)](n), there are two independent La(III) atoms which are coordinated differently in slightly distorted penta-gonal-bipyramidal and slightly disorted bicapped trigonal-prismatic environments. The La(III) ions are bridged by ?(4)-isophthalate ligands, forming two-dimensional layers. In the crystal structure, these layers are connected by inter-molecular O-H?O hydrogen bonds into a three-dimensional network.

Poly[triaqua-tris-(μ(4)-pyridine-3,5-dicarboxyl-ato)dicerium(III)].

Project description:The asymmetric unit of the title compound, [Ce(2)(C(7)H(3)NO(4))(3)(H(2)O)(3)](n), contains two Ce(III) cations, three pyridine-3,5-dicarboxyl-ate (pyd) anions and three coordinated water mol-ecules. One Ce(III) cation is coordinated by seven carboxyl-ate O atoms from six pyd anions and two water mol-ecules in a square-face-capped square-anti-prismatic geometry. Another Ce(III) cation is coordinated by seven O atoms from six pdy anions and one water mol-ecule in a bicapped trigonal-prismatic geometry. The pdy anions bridge the Ce(III) cations, forming the three-dimensional polymeric structure. The crystal structure contains extensive O-H⋯O, O-H⋯N and weak C-H⋯O hydrogen bonds. π-π stacking is present in the crystal structure, the shortest centroid-centroid distance between parallel pyridine rings being 3.509 (4) Å.

Eight Nd(III) ions and 12 pda ligands form a large [Nd(8)(pda)(12)] ring, and four Nd(III) ions and six pda ligands form a small [Nd(4)(pda)(6)] ring. These rings are further connected by the coordination inter-actions of pda ligands and Nd(III), generating a three-dimensional supra-molecular framework.

The 5-hy-droxy-isophthalate anions bridge the Gd cations, forming a layer structure.

catena-Poly[diaqua-tris(?(3)-biphenyl-2,2-dicarboxyl-ato)disamarium(III)].

Project description:The title compound, [Sm(2)(C(14)H(8)O(4))(3)(H(2)O)(2)](n), is composed of one-dimensional chains and is isostructural with previously reported compounds [Wang et al. (2003 ?). Eur. J. Inorg. Chem. pp. 1355-1360]. The asymmetric unit contains two Sm atoms, each of which lies on a crystallographic twofold axis. Both crystallographically independent Sm atoms are coordinated by eight O atoms in a distorted dodeca-hedral arrangement. The polymeric chains run along [001]. Adjacent chains are connected through ?-? inter-actions [centroid-centroid distance = 3.450?(2)?Å], forming a two-dimensional supra-molecular network.

catena-Poly[[[diaqua-terbium(III)]-tri-?(2)-isonicotinato-?O:O'] tris(perchlorate) monohydrate].

Project description:In the title complex, {[Tb(C(6)H(5)NO(2))(3)(H(2)O)(2)](ClO(4))(3)·H(2)O}(n), the Tb(III) ion is coordinated by six O atoms from six isonicotinate (inic) ligands and two water mol-ecules, displaying a bicapped trigonal-prismatic geometry. The inic ligands, which are protonated at the pyridine N atom, link the metal centres, forming a polymeric chain running parallel to the a axis. The chains are further assembled via intra- and inter-molecular O-H?O and N-H?O hydrogen-bonding inter-actions into a three-dimensional supra-molecular network involving the inic ligands, the water mol-ecules and the perchlorate anions. One of the perchlorate ions is disordered over two sites with occupancies of 0.561?(17) and 0.439?(17).

Redetermination of dicerium(III) tris-(sulfate) tetra-hydrate.

Project description:Ce(2)(SO(4))(3)(H(2)O)(4) was obtained hydro-thermally from an aqueous solution of cerium(III) oxide, trimethyl-amine and sulfuric acid. The precision of the structure determination has been significantly improved compared with the previous result [Dereigne (1972 ?). Bull. Soc. Fr. Mineral. Cristallogr.95, 269-280]. The coordination about the two Ce atoms is achieved by seven and six bridging O atoms from sulfate anions. Each S atom makes four S-O-Ce linkages through bridging O atoms. The coordination sphere of each Ce is completed by two water molecules, which act as terminal ligands.

Poly[diaqua-bis(2,2'-bipyridine)tris-(?(4)-2,2'-bipyridine-4,4'-dicarboxyl-ato)dineodymium(III)].

Project description:In the crystal structure of the title mixed-ligand coordination polymer, [Nd(2)(C(12)H(6)N(2)O(4))(3)(C(10)H(8)N(2))(2)(H(2)O)(2)](n), the Nd(III) ion is in an octa-hedral coordination environment formed by one water mol-ecule, one chelating 2,2'-bipyridine ligand, and five monodentate carboxyl-ate groups. The local coordination polyhedron around the Nd(III) ion is a bicapped trigonal prism. Two Nd(III) centers are bridged by four carboxyl-ate groups to form an Nd(2) dimeric unit; these are further connected by 2,2'-bipyridine-4,4'-dicarboxyl-ate linkers, resulting in a layered coordination network.
