Poly[aqua(μ2-oxalato)(4-oxidopyridinium)erbium(II)]
The title complex, [Er(C(5)H(5)NO)(C(2)O(4))(H(2)O)](n), is a new erbium polymer based on oxalate and 4-oxidopyridinium ligands. The Er(II) center is coordinated by six O atoms from three oxalate ligands, one O atom from a 4-oxidopyridinium ligand and one water mol-ecule, and displays a distorted square-anti-prismatic coordination geometry. The oxalate ligands are both chelating and bridging, a...

The title compound, {[Er2(C4H2O4)2(C2O4)(H2O)4]·4H2O} n , was synthesized by the reaction of erbium nitrate hexa-hydrate with fumaric acid and oxalic acid under hydro-thermal conditions. The Er(3+) cation (site symmetry ..2) is eight-coordinated by six O atoms from four fumarate anions (site symmetry ..2) and one bidentate oxalate anion (site symmetry 222), and by two water mol-ecules. The comp...

In the title coordination polymer, [Ba(C5HN2O6)(C2O4)0.5(H2O)2] n , the tenfold coordination of the Ba centre consists of four O atoms from the two 4-nitro-2,5,6-trioxo-1,2,5,6-tetra-hydro-pyridin-3-olate (L) anions, three O atoms of two oxalate anions and three water mol-ecules. The Ba-O bond lengths fall in the range 2.698 (3)-2.978 (3) Å. The L ligand chelates two Ba atoms related by a screw...
متن کاملPoly[aqua[μ2-1,1′-(butane-1,4-diyl)diimidazole](μ2-naphthalene-1,4-dicarboxylato)nickel(II)]
In the title compound, [Ni(C(12)H(6)O(4))(C(10)H(14)N(4))(H(2)O)](n), the coordination polyhedron around each Ni(II) atom is a distorted cis-NiN(2)O(4) octa-hedron. The naphthalene-1,4-dicarboxyl-ate and 1,1'-(butane-1,4-di-yl)diimidazole ligands bridge the Ni centres to form a two-dimensional (4,4)-network, and O-H⋯O hydrogen bonds complete the structure.
