catena-Poly[[bis(N,N′-dimethylformamide)cadmium(II)]-μ2-oxalato]
The title compound, [Cd(C(2)O(4))(C(3)H(7)NO)(2)](n), is isostructural with its Mn(II) analogue. The structure comprises zigzag polymeric chains with the oxalate groups situated on inversion centres and the Cd(II) atoms located on twofold rotation axes. The coordination geometry around Cd(II) is distorted octa-hedral and the intra-chain Cd⋯Cd distance is 5.842 (1) Å. C-H⋯O hydrogen bonds exist ...

In the title compound, {[AgSm(C(6)H(4)NO(2))(2)(C(2)O(4))]·H(2)O}(n), the asymmetric unit contains one Sm(III) ion, one Ag(I) ion, two unique isonicotinate (ina) ligands, two half oxalate (ox) ligands (one on an inversion centre, the other on a twofold axis) and one uncoordinated water mol-ecule. The central Sm(III) ion is nine-coordinated by four O-donor atoms from separate bidentate bridging ...

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 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...

In the title compound, {[Pr(2)(C(2)O(4))(3)(H(2)O)(4)]·2H(2)O}(n), the three-dimensional network structure has the Pr(III) ion coordinated by nine O atoms in a distorted tricapped trigonal-prismatic geometry. The coordinated and uncoordinated water mol-ecules inter-act with the carboxyl-ate O atoms to consolidate the network via O-H⋯O hydrogen bonds.
