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

ABSTRACT: 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.

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 μ- and μ(3)-O atoms. Thus, inorganic Er-O-Er layers of edge- and face-sharing polyhedra are observed.

Project description:The crystal structure of the title compound, [Cu(2)(C(2)H(4)O(6)PS)(OH)(H(2)O)(2)]·3H(2)O, consists of two Cu(2+) ions, one (O(3)PC(2)H(4)SO(3))(3-) ion and one OH(-) ion, as well as five water mol-ecules, two of which are coordinated to Cu(2+). The Cu(2+) ions are coordinated by six O atoms. The CuO(6) polyhedra are connected by μ- and μ(3)-O atoms into zigzag chains along the b axis. These chains are further connected by -CH(2)CH(2)- groups to form layers, in turn building a three-dimensional framework via hydrogen bonding.

Poly[[tetra-aqua-(μ(4)-imidazole-4,5-dicarboxyl-ato)(μ(3)-imidazole-4,5-dicarboxyl-ato)-μ(3)-sulfato-μ(2)-sulfato-cobalt(II)dierbium(III)] monohydrate].

Project description:The asymmetric unit of the title compound, {[CoEr(2)(C(5)H(2)N(2)O(4))(2)(SO(4))(2)(H(2)O)(4)]·H(2)O}(n), contains a Co(II) ion, two Er(III) ions, two imidazole-4,5-dicarboxyl-ate (imdc) ligands, two SO(4) (2-) anions, four coordinated water mol-ecules and one uncoordinated water mol-ecule. The Co(II) ion is six-coordinated by two O atoms from two coordinated water mol-ecules and two O atoms and two N atoms from two imdc ligands in a slightly distorted octa-hedral geometry. Both Er(III) ions are eight-coordinated in a bicapped trigonal-prismatic coordination geometry. One Er(III) ion is coordinated by four O atoms from two imidazole-4,5-dicarboxyl-ate ligands, three O atoms from three SO(4) (2-) anions and one water O atom; the other Er(III) ion is bonded to five O atoms from three imdc ligands, two O atoms from two SO(4) (2-) anions as well as one coordinated water mol-ecule. The coordinated metal units are connected by bridging imdc ligands and sulfate ions, generating a two-dimensional heterometallic layer. The two-dimensional layers are stacked along the b axis via N-H⋯O, O-H⋯O and C-H⋯O hydrogen-bonding inter-actions between water mol-ecules, SO(4) (2-) anions, and imdc ligands, generating a three-dimensional framework.

Project description:The title compound, {[Co(C(2)H(5)COO)(2)(H(2)O)]·H(2)O}(n), was synthesized by the reaction of cobalt(II) carbonate hydrate with aqueous propionic acid. The structure consists of polymeric infinite linear chains with composition [Co(C(2)H(5)COO)(4/2)(H(2)O)(2/2)](∞) running along [010]. The chains are formed by Co(2+) ions linked with bridging propionate groups and water mol-ecules, with a Co⋯Co distance along the chains of 3.2587 (9) Å. The Co(2+) ion is six-coordinated in a strongly distorted octa-hedral geometry. The chains are connected to each other by a network of O-H⋯O hydrogen bonds involving solvent water mol-ecules.

catena-Poly[[[aqua-(1,10-phenanthro-line)manganese(II)]-μ-adamantane-1,3-dicarboxyl-ato] monohydrate].

Project description:In the title coordination polymer, {[Mn(C(12)H(14)O(4))(C(12)H(8)N(2))(H(2)O)]·H(2)O}(n), the Mn(II) atom has a highly distorted cis-MnN(2)O(4) octa-hedral geometry arising from its coordination by a bidentate phenanthroline ligand, a water mol-ecule and monodentate and bidentate adamantane-1,3-dicarboxyl-ate dianions. The bridging dianion leads to [001] chains in the crystal. The chains are linked by O-H⋯O hydrogen bonds, involving both the coordinated and uncoordinated water mol-ecules, thereby forming a two-dimensional network.

Poly[piperazinediium [[aqua-bismuth-ate(III)]-di-μ-pyridine-2,6-dicarboxyl-ato-bis-muthate(III)-di-μ-pyridine-2,6-dicarboxyl-ato] monohydrate].

Project description:The title compound, {(C(4)H(12)N(2))[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)]·H(2)O}(n) or {(pipzH(2))[Bi(2)(pydc)(4)(H(2)O)]·H(2)O}(n), where pydcH(2) is pyridine-2,6-dicarboxylic acid and pipz is piperazine, was obtained by reaction of Bi(NO(3))(3)·5H(2)O with (pipzH(2))(pydc-H)(2)·3H(2)O in a 1:2 molar ratio in aqueous solution. There are two independent Bi(III) atoms in the structure, one of which is eight-coordinate with a distorted bicapped trigonal-prismatic geometry, and another which is nine-coordinate with a distorted tricapped trigonal-prismatic geometry. The carboxyl-ate groups of the (pydc)(2-) ligands link dinuclear [Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)](2-) units into one-dimensional coordin-ation polymers. The pipzH(2) (2+) cations (site symmetry ) and non-coordinated water mol-ecules lie between these polymers, forming N-H⋯O and O-H⋯O hydrogen bonds to the O atoms of the carboxylate groups.

4,4'-Bipyridinium bis-(μ-4-oxo-1,4-dihydropyridine-2,6-dicarboxyl-ato)bis-[aqua-hydroxido-anti-monate(III)] dihydrate.

Project description:The title compound, (C(10)H(10)N(2))[Sb(2)(C(7)H(2)NO(5))(2)(OH)(2)(H(2)O)(2)]·2H(2)O, consists of a binuclear anion, a diprotonated 4,4'-bipyridinium cation and two uncoordinated water mol-ecules. Each Sb(III) atom is six-coordinated by one chelating 4-oxidopyridine-2,6-dicarboxyl-ate ligand, one water mol-ecule, one OH group and one bridging O atom from a neighboring carboxyl-ate group in a distorted penta-gonal-pyramidal geometry, with the OH group at the apical position. The two pyridine rings in the bipyridinium cation are twisted with respect to each other, making a dihedral angle of 22.7 (1)°. The cations are connected to the anions by N-H⋯O hydrogen bonds, forming a chain. The coordinated water mol-ecules form hydrogen bonds with the oxido O atoms of the anion, building a two-dimensional sheet, which is further connected into a three-dimensional structure by O-H⋯O and C-H⋯O hydrogen bonds and C=O⋯π inter-actions [O⋯centroid distances = 3.1785 (17), 3.4737 (19) and 3.5685 (19) Å].

Project description:In the title compound, {[Sr(C(12)H(10)O(12))(H(2)O)]·H(2)O}(n), the Sr(II) ion is coordinated by six O atoms of five symmetry-related 3,4,5,6-tetra-carb-oxy-cyclo-hexane-1,2-dicarboxyl-ate ligands and one water mol-ecule in a slightly distorted monocapped trigonal-prismatic environment. The ligands bridge the Sr(II) ions, forming a two-dimensional structure. In the crystal, O-H⋯O hydrogen bonds further connect the structure into a three-dimensional network. The H atoms of two of the carboxyl groups were refined as half-occupancy.

Poly[μ(2)-aqua-aqua-μ(4)-pyridine-2,4-dicarboxyl-ato-strontium].

Project description:In the title polymeric complex, [Sr(C(7)H(3)NO(4))(H(2)O)(2)](n), the Sr(II) atom is eight-coordinated by four O atoms and one N atom of four pyridine-2,4-dicarboxyl-ate (py-2,4-dc) ligands and three O atoms of three coordinated water mol-ecules in a dodeca-hedral geometry. These units are connected via the carboxyl-ate O atoms and water mol-ecules, building polymeric layers parallel to (100). In the crystal structure, non-covalent inter-actions consisting of O-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distances = 3.862 (17) and 3.749 (17) Å] connect the various components, forming a three-dimensional structure.
