Poly[di-₃-aqua-₄-terephthalato-dicaesium]

I. Stein and U. Ruschewitz

Abstract: Colourless platelets of dicaesium terephthalate dihydrate, [Cs₂(C₈O₄H₄)(H₂O)₂]_n, were obtained from an aqueous solution of Cs₂CO₃, NaOH and terephthalic acid in demineralized water and subsequent evaporation of the solvent at room temperature. Caesium is coordinated by four O atoms from four water molecules and four O atoms from four different centrosymmetric terephthalates. The metal centres are connected by the water molecules, forming a double layer parallel to (011). These double layers are linked by the terephthalate dianions, forming a three-dimensional framework structure.
