Abstract
Three new phosphonoacetate hybrid frameworks based on the actinide elements uranium and thorium have been synthesized. The compounds [C4N2H14] [(UO2)2(O3PCH2COO)2]· H2O, I, [C4N2H14] [(UO2)2(C2O4)(O3PCH2COOH) 2], II, and Th(H2O)2(O3PCH2COO) (C2O4)0.5·H2O, III, are built up from the connectivity between the metal polyhedra and the phosphonoacetate/oxalate units. Compound II has been prepared using a solvent-free approach, by a solid state reaction at 150°C. It has been shown that II can also be prepared through a room temperature mechanochemical (grinding) route. The layer arrangement in III closely resembles to that observed in I. The compounds have been characterized by powder X-ray diffraction, IR spectroscopy, thermogravimetric analysis, and fluorescence studies.
