摘要：

The gamma-zirconium phosphate phosphonates, ZrPO4(H2PO4)1-x(RPO2OH)x.nH2O (R = CH3, C3H7, C6H11), have been prepared by total or partial replacement of the interlayer dihydrogen phosphate groups of gamma-ZrPO4H2PO4.2H2O with RPO2(OH)- groups of the corresponding phosphonic acids. The following compounds: gamma-ZrPO4CH3PO2OH.2H2O (interlayer distance = 12.8 angstrom); gamma-ZrPO4C3H7PO2OH.1.2H2O (interlayer distance = 15.1 angstrom) and gamma-ZrPO4(H2PO4)0.33(C6H11PO2OH)0.67.H2O (interlayer distance = 16.9 angstrom) were obtained. The partial replacement of H2PO4- groups when cyclohexyl phosphonic acid was used seems to be due to steric hindrances in the interlayer region. Some considerations on the structure of these compounds as well as some preliminary ion exchange and intercalation properties are also reported.
