Ionothermal synthesis and magnetic studies of novel two-dimensional metal-formate frameworks.

Five novel two-dimensional frameworks containing formate-bridged metal-centered octahedra are synthesized ionothermally from two ionic liquids previously unused as solvents in hybrid synthesis, 2-hydroxyethylammonium (HEA) formate, and 1-hydroxy-3-proplyammonium (HPA) formate. Templating effects of the cation from each ionic liquid drive the formation of different structures. [NH(3)C(2)H(4)OH](2)[M(CHO(2))(4)] (1: M = Co, 2: M = Ni) exhibit the same stoichiometry and connectivity as their manganese analogue (3: M = Mn), but the manganese form exhibits a different topology from 1 and 2.

Anionic gallium-based metal-organic framework and its sorption and ion-exchange properties.

A gallium-based metal-organic framework Ga(6)(C(9)H(3)O(6))(8)·(C(2)H(8)N)(6)(C(3)H(7)NO)(3)(H(2)O)(26) [1, Ga(6)(1,3,5-BTC)(8)·6DMA·3DMF·26H(2)O], GaMOF-1; BTC = benzenetricarboxylate/trimesic acid and DMA = dimethylamine], with space group I43d, a = 19.611(1) Å, and V = 7953.4(6) Å(3), was synthesized using solvothermal techniques and characterized by synchrotron-based X-ray microcrystal diffraction.

Poly[bis-(N,N-dimethyl-formamide-κO)(μ(4)-naphthalene-1,5-disulfonato)magnesium(II)].

The structure of the title compound, [Mg(C(10)H(6)O(6)S(2))(C(3)H(7)NO)(2)](n), consists of MgO(6) octa-hedra ( symmetry) connected to naphthalene-1,5-disulfonate ligands ( symmetry) in the equatoral plane, forming a two-dimensional network propagating parallel to (010). The coordination sphere of the Mg atom is completed by the O atoms of two N,N-dimethyl-formamide (DMF) mol-ecules in the axial positions. The title compound represents the first time the naphthalene-1,5-disulfonate anion is bound directly to a Mg(2+) atom.

Poly[[aquaneodymium(III)]-micro(3)-decane-1,10-dicarboxylato-micro(3)-9-carboxynonanecarboxylato].

The title compound, [Nd(C(10)H(16)O(4))(C(10)H(17)O(4))(H(2)O)](n), has a novel Nd-organic framework constructed from sebacic acid (C(10)H(18)O(4)) linkers, the longest aliphatic ligand used to date in lanthanide metal-organic framework compounds. The structure contains edge-shared chains of NdO(8)(H(2)O) tricapped trigonal prisms that propagate in the [100] direction, with Nd-O distances in the range 2.414 (4)-2.

Topological evolution in uranyl dicarboxylates: synthesis and structures of one-dimensional UO2(C6H8O4)(H2O)2 and three-dimensional UO2(C6H8O4).

Two novel uranyl adipates are reported as synthesized via hydrothermal treatment of uranium oxynitrate and adipic acid. One-dimensional UO(2)(C(6)H(8)O(4))(H(2)O)(2) (1) [a = 9.6306(6) A, c = 11.
