Poly[hexa-aqua-tri-?-malonato-didysprosium(III)].

ABSTRACT: The title compound, [Dy(2)(C(3)H(2)O(4))(3)(H(2)O)(6)](n), forms a coordination polymeric structure comprising hydrated dysprosium ions and malonate ligands. In the asymmetric unit, there are one dysprosium ion, one and a half malonate ligands, and three water mol-ecules. Each Dy(III) atom is coordinated by six O atoms from four malonate ligands and by three water mol-ecules, and displays a tricapped trigonal-prismatic coordination geometry. The malonate ligands adopt two types of coordination mode, linking dysprosium centres to form a three-dimensional coordination polymer. The extensive network of hydrogen bonds in this polymer enhances the structural stability.

Hexa-aqua-nickel(II) bis-[tri-aqua-?3-oxalato-di-?-oxalato-bariumchromate(III)] tetra-hydrate.

Project description:The title compound, [Ni(H2O)6][BaCr(C2O4)3(H2O)3]2·4H2O, was obtained in the form of single crystals from the slow evaporation of an aqueous mixture of {Ba6(H2O)17[Cr(C2O4)3]4}·7H2O and NiSO4·6H2O in the molar ratio 1:4. Its structure is made up of corrugated anionic (101) layers of formula [BaCr(C2O4)3(H2O)3] n n - that leave voids accommodating the charge-compensating cations, [Ni(H2O)6]2+ (point group symmetry ), as well as the water mol-ecules of crystallization. The anionic layers are built from the connection of barium and chromium atoms through bridging oxalate ligands. The CrIII atom is hexa-coordinated by O atoms of three oxalate ligands while the BaII atom is tenfold coordinated by three O atoms of water mol-ecules and seven O atoms of four oxalate ligands. Each NiII atom sits on an inversion center and is coordinated by six water mol-ecules. One of the uncoordinated water mol-ecules is disordered over two sites, with a refined occupancy ratio of 0.51?(5):0.49?(5). In the crystal, extensive O-H?O hydrogen-bonding inter-actions link the anionic layers, the charge-balancing cations as well as the water mol-ecules of crystallization into a three-dimensional supra-molecular network.

Poly[hexa-aqua-hexa-kis-(?-pyridine-2,4-dicarboxyl-ato)tricopper(II)dieuropium(III)].

Project description:The asymmetric unit of the title heterometallic coordination polymer, [Cu(3)Eu(2)(C(7)H(3)NO(4))(6)(H(2)O)(6)](n), contains one Eu(III) and two Cu(II) atoms, three pyridine-2,4-dicarboxylate (pdc)(2-) anions and three water molecules. One Cu(II) atom is located on an inversion center and is N,O-chelated by two pdc(2-) anions in the equatorial plane and further coordinated by two carboxyl-ate O atoms from another two pdc anions in the axial positions, with an elongated octa-hedral geometry [Cu-O = 2.409?(3)?Å in the axial direction]; the other Cu atom is N,O-chelated by two pdc anions in the coordination basal plane and coordinated by a carboxyl O atom at the apical position with a distorted square-pyramidal geometry [Cu-O = 2.359?(3)?Å in the apical direction]. The Eu atom is eight-coordinated with a distorted square-anti-prismatic geometry formed by five carboxyl-ate O atoms from five pdc anions and three water mol-ecules. The carboxyl-ate anions bridge adjacent Eu and Cu atoms, forming the coordination polymer. Inter- and intra-molecular O-H?O hydrogen bonding occurs in the structure. ?-? stacking further consolidates the crystal structure, the centroid-centroid distance between parallel pyridine rings being 3.367?(2)?Å.

Project description:The three-dimensional title coordination polymer, {[Tb(2)(C(8)H(2)NO(6))(2)(H(2)O)(5)]·H(2)O}(n), was hydro-thermally synthesized by reacting the corresponding rare-earth salt with pyridine-2,4,6-tricarb-oxy-lic acid (H(3)ptc).

The complex units are inter-connected through the ptc(3-) anions acting in different coordination modes, resulting in a three-dimensional coordin-ation polymer. The crystal structure features extensive O-H?O hydrogen bonds.

The ptc ligands brigde the Sm(III) ions into a three-dimensional polymeric framework. Extensive O-H?O hydrogen bonding is observed in the crystal structure.

Poly[[aqua-tri-?(3)-hydroxido-(?(4)-2-phos-phon-ato-ethane-sulfonato)-dierbium(III)] monohydrate].

Project description:The crystal structure of the title compound, {[Er(2)(C(2)H(4)O(6)PS)(OH)(3)(H(2)O)]·H(2)O}(n), consists of two Er(3+) ions, one (C(2)H(4)O(6)PS)(3-) ion, three OH(-) ions, and two water mol-ecule. The Er(3+) ions form ErO(8) polyhedra., which are connected by ?- and ?(3)-O atoms. Thus, inorganic Er-O-Er layers of edge- and face-sharing polyhedra are observed. Whereas most often in metal phosphono-sulfonates the organic linker bridges adjacent layers, in the title compound, the (O(3)PC(2)H(4)SO(3))(3-) anion is only connected to one Er-O-Er layer. Short interatomic O?O distances [2.898?(8), 2.997?(14) and 2.768?(10)?Å] indicate hydrogen bonding between the layers. The noncoordinated water mol-ecules are located between the layers.

catena-Poly[[aqua-(4-ethyl-benzoic acid-κO)lanthanum(III)]-tri-μ-4-ethyl-benzoato].

Project description:The reaction of lanthanum nitrate and 4-ethyl-benzoic acid (EBAH) in aqueous solution yielded the title polymer, [La(C(9)H(9)O(2))(3)(C(9)H(10)O(2))(H(2)O)](n). The asymmetric unit contains one La(III) atom, three 4-ethyl-benzoate (EBA) ligands, one neutral EBAH ligand and one coordinated water mol-ecule. Each La(III) ion is eight-coordinated by six O atoms from six bridging-bidentate EBA ligands, one O atom from a monodentate EBAH ligand and one water O atom in a distorted bicapped trigonal-prismatic geometry. The adjacent La(III) ions are linked by the carboxyl-ate groups of EBA ligands in a bridging-bidetate coordination mode, resulting in an infinite chain structure along the c axis. O-H⋯O hydrogen-bonding inter-actions involving the water mol-ecules, carboxyl-ate groups and carboxyl H atoms are formed within the one-dimensional polymer. One of the ethyl groups is disordered over two positions with occupancies of 0.717 (7) and 0.283 (7).
