Poly[μ2-aqua-aqua-μ4-pyridine-2,4-dicarboxylato-strontium]
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). ...
متن کاملPoly[μ-aqua-μ4-terephthalato-strontium]
In the title compound, [Sr(C(8)H(4)O(4))(H(2)O)](n), the Sr(II) atom exhibits coordination number eight, with six O atoms from four carboxylate groups (two bidentate and two monodentate) of terephthalate ligands and two water O atoms. The SrO(8) polyhedra are linked into inorganic chains by sharing three coplanar O atoms. These inorganic chains are extended along the b axis to form layers in th...

In the crystal structure of the polymeric title compound, [Sr(C(10)H(6)O(6)S(2))(H(2)O)(2)](n), the naphthalene-2,7-disulfonate dianion uses one -SO(3) unit to bind to two Sr(II) cations and the other -SO(3) unit to bind to three Sr(II) cations; of the two coordinated water mol-ecules, one is monodentate to one Sr(II) cation, whereas the other bridges two Sr(II) cations. The μ(5)-bridging mode ...
متن کاملPoly[[μ2-aqua-tetraaquahexakis(μ4-naphthalene-2,6-dicarboxylato)tetraholmium(III)] 1.75-hydrate]
In the title compound, {[Ho(4)(C(12)H(6)O(4))(6)(H(2)O)(5)]·1.75H(2)O}(n), which is isostructural with its Tb(3+)- and Eu(3+)-containing analogues, there are four crystallographically independent Ho(3+) centres, each exhibiting a highly distorted HoO(8) bicapped trigonal-prismatic coordination environment. Adjacent polyhedra are inter-connected via the carboxyl-ate groups and one μ(2)-bridging ...
متن کاملPoly[μ-aqua-aqua-μ4-naphthalene-1,8-dicarboxylato-barium]: a layer structure
The title compound, [Ba(C12H6O4)(H2O)2] n , is represented by a layer-like structure built of BaO8 polyhedra. The asymmetric unit contains a Ba(2+) ion, half a coordinating water mol-ecule and half a μ4-bridging naphthalene-1,8-dicarboxyl-ate (1,8-nap) ligand, the whole structure being generated by twofold rotational symmetry. The carboxyl-ate groups of the 1,8-nap ligands act as bridges linkin...
