Poly[[hemi-μ4-oxalato-hemi-μ2-oxalato-bis(μ3-pyrazine-2-carboxylato)erbium(III)silver(I)] monohydrate]
The asymmetric unit of the title complex, {[AgEr(C(5)H(3)N(2)O(2))(2)(C(2)O(4))]·H(2)O}(n), contains one Er(III) atom, one Ag(I) atom, two pyrazine-2-carboxyl-ate (pyc) ligands, two half oxalate ligands (each lying on an inversion center) and one uncoordinated water mol-ecule. The Er(III) atom is coordinated by two O atoms and two N atoms from two pyc ligands, one O atom from a third pyc ligand...

In the title coordination polymer, {[AgNd(C(5)H(3)N(2)O(2))(2)(C(2)O(4))]·H(2)O}(n), the Nd(III) atom is coordinated in a distorted monocapped square-anti-prismatic geometry by two O and two N atoms of two N,O-bidentate pyrazine-2-carboxyl-ate (2-pzc) ligands, four O atoms of two bidentate oxalate ligands, and one O atom of a monodentate carboxyl-ate group of a 2-pzc ligand. The Ag(I) ion is co...

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 occup...

The asymmetric unit of the title compound, {[AgNd(C(6)H(4)NO(2))(2)(C(2)O(4))]·2H(2)O}(n), contains one Nd(III) atom, one Ag(I) atom, one oxalate ligand, two nicotinate ligands and two uncoordinated water mol-ecules. The Nd(III) atom is eight-coordinated in a distorted square-anti-prismatic coordination geometry by four O atoms from two oxalate ligands and four O atoms from four nicotinate liga...

The title compound, [Cu(2)(C(2)O(4))(2)(C(3)H(4)N(2))(2)](n), was obtained as an unexpected product under hydro-thermal conditions. The Cu(II) atom is in a Jahn-Teller-distorted octa-hedral environment formed by one imidazole N atom and five O atoms from three oxalate anions. The two independent oxalate anions are situated on centres of inversion and coordinate to the Cu(II) atom in two differe...
