This paper reports the preparation and characterization of a series of organic derivatives of ZrPO4Cl(CH3)2SO obtained by topotactic anion exchange of chloride ligands with several n-alkoxide (RO) and carboxylate groups (RCOO). Exchange with alkoxides, with an alkyl chain length from 2 to 8 carbon atoms, gave products of general formula ZrPO4RO(CH3)2SO. In these derivatives alkoxide groups, covalently bonded to zirconium atoms via Zr-O bonds, point toward the interlayer region. Carboxylate derivatives, of general formula ZrPO 4[(RCOO)(CH3)2SO]1-x(OH H 2O)x, were obtained using benzoate (x = 0), nitrobenzoate (x = 0.3), and phenylacetate (x = 0.2) groups. The thermal behavior of these organic derivatives is discussed. Due to this reactivity, ZrPO 4Cl(CH3)2SO is an attractive precursor for materials chemistry.
