In the title compound, [CaCs2(C2O4)2(H2O)4] n , the Ca(2+) ion, lying on a twofold rotation axis, is coordinated by four O atoms from two oxalate ligands and two bridging water mol-ecules in an octa-hedral geometry. The Cs(+) ion is coordinated by seven O atoms from six oxalate ligands, one bridging water and one terminal water mol-ecule. The oxalate ligand(More)
Correlative studies of three oxalato-bridged polymers, obtained under hydrothermal conditions for the two isostructural compounds ⎨Rb 1 , 2, and by conventional synthetic method for ⎨Rb(HC 2 O 4)⎬ ∞ 3 , 3, allowed the identification of H-bond patterns and structural dimensionality. Ferroïc domain structures are confirmed by electric measurements performed(More)
