Poly[[aqua-(?(2)-oxalato)(?(2)-2-oxido-pyridinium-3-carboxylato)holmium(III)] monohydrate].

ABSTRACT: In the title complex, {[Ho(C(2)O(4))(C(6)H(4)NO(3))(H(2)O)]·(H(2)O)}(n), the Ho(III) ion is coordinated by three O atoms from two 2-oxidopyridinium-3-carboxylate ligands, four O atoms from two oxalate ligands and one water mol-ecule in a distorted bicapped trigonal-prismatic geometry. The 2-oxidopyridin-ium-3-carboxylate and oxalate ligands link the Ho(III) ions into a layer in (100). These layers are further connected by inter-molecular O-H?O hydrogen bonds involving the coordinated water mol-ecules to assemble a three-dimensional supra-molecular network. The uncoordin-ated water mol-ecule is involved in N-H?O and O-H?O hydrogen bonds within the layer.

The uncoordinated water mol-ecule is involved in N-H?O and O-H?O hydrogen-bonding inter-actions within the layer.

Poly[?-5-ammonio-isophthalato-aqua-?-oxalato-dysprosium(III)].

Project description:The title complex, [Dy(C(8)H(6)NO(4))(C(2)O(4))(H(2)O)](n), is a dysprosium coordination polymer with mixed anions and was obtained under hydrothermal conditions. In the structure, the oxalate and 5-amino-isophthalate ligands link the dysprosium ions, building up a two-dimensional metal-organic framework parallel to the (10) plane. These sheets are further connected through O-H?O, N-H?O and C-H?O hydrogen bonds, forming a three-dimensional supra-molecular structure.

Poly[[tetra-aqua-di-?(4)-oxalato-?(2)-oxalato-dineo-dymium(III)] dihydrate].

Project description:The title compound, {[Nd(2)(C(2)O(4))(3)(H(2)O)(4)]·2H(2)O}(n), was synthesized hydro-thermally in the presence of bis-(carb-oxy-ethyl-germanium) sesquioxide. It is isostructural with the corresponding Pr compound [Yang et al. (2009). Acta Cryst. E65, m1152-m1153]. The Nd(3+) cation is nine-coordinated and its coordination polyhedron can be described as a distorted tricapped trigonal prism. Two Nd(3+) ions are connected by two O atoms from two oxalate ions to give a dinuclear Nd(2) unit. The unit is further linked to four others via four oxalate ions yielding a layerparallel to (0-11). The linkages between the layers by neighbouring oxalate anions lead to a three-dimensional framework with channels along the c axis. The coordinating and free water mol-ecules are located in the channels and make contact with each other and the host framework by weak O-H?O hydrogen bonds.

Poly[[diaqua-hemi-μ(4)-oxalato-μ(2)-oxalato-praseodymium(III)] monohydrate].

Project description:In the title complex, {[Pr(C(2)O(4))(1.5)(H(2)O)(2)]·H(2)O}(n), the Pr(III) ion, which lies on a crystallographic inversion centre, is coordinated by seven O atoms from four oxalate ligands and two O atoms from two water ligands; further Pr-O coordination from tetra-dentate oxalate ligands forms a three-dimensional structure. The compound crystallized as a monohydrate, the water mol-ecule occupying space in small voids and being secured by O-H⋯O hydrogen bonding as an acceptor from ligand water H atoms and as a donor to oxalate O-acceptor sites.

Poly[aqua(?(3)-5-aza-niumylisophthalato)-(?-oxalato)neodymium(III)].

Project description:The title compound, [Nd(C(8)H(6)NO(4))(C(2)O(4))(H(2)O)](n), is a layer-like coordination polymer. The Nd(III) ion is coordinated by four carboxyl-ate O atoms from three bridging 5-aza-nium-yl-isophthalate (Haip) ligands, four carboxyl-ate O atoms from two oxalate (ox) anions and one ligated water mol-ecule in a tricapped trigonal-prismatic geometry. The Haip anion acts as a ?(3)-bridge, connecting three Nd(III) ions through two carboxyl-ate groups; the ox anion adopts a bis-bidentate-bridging mode, linking two Nd(III) ions. The layer framework is further extended to a three-dimensional supra-molecular structure through N-H?O and O-H?O hydrogen bonds.

4-(Dimethyl-amino)-pyridinium octa-aqua-erbium(III) tetra-chloride monohydrate.

Project description:In the title compound, (C(7)H(11)N(2))[Er(H(2)O)(8)]Cl(4)·H(2)O, the asymmetric unit consists of one 4-(dimethyl-amino)-pyridinium and one octa-aqua-erbium cation balanced by four Cl(-) anions, and one water mol-ecule.

In the crystal, the [Er(H(2)O)(8)](3+) cations are linked via O-H⋯O and O-H⋯Cl hydrogen bonds, forming two-dimensional networks propagating in the ab plane. These networks are linked via O-H⋯O and O-H⋯Cl hydrogen bonds, forming a three-dimensional network. The 4-(dimethyl-amino)-pyridinium cations are located in the cavities and are linked to the framework via N-H⋯Cl, C-H⋯O and C-H⋯Cl hydrogen bonds.

Monoclinic polymorph of poly[[di-μ-aqua-triaquadi-μ-oxalato-barium(II)-copper(II)] monohydrate].

Project description:A monoclinic polymorph of the title compound, {[BaCu(C(2)O(4))(2)(H(2)O)(5)]·H(2)O}(n), is reported. The structure is best described as a coordination polymer where the Cu(II) and Ba(II) centers are coordinated by five and nine O atoms, respectively, in capped quadratic antiprismatic and tetragonal pyramidal geometries. The polymerization arises due to the presence of bridging mono- and bidentate oxalate ligands as well as bridging water mol-ecules. The crystal structure is consolidated by a three-dimensional network of hydrogen bonding.
