Th(IV)
readily undergoes hydrolysis and condensation in aqueous
solutions to form polynuclear molecular species and the system becomes
increasingly complicated when organic chelators or other metals are
present in solution, leading to the formation of complexes with vastly
different structural topologies. Five compounds containing binary
and ternary Th(IV) complexes have been synthesized and structurally
characterized using single-crystal X-ray diffraction, including Na4[Th6O2(C10O7N2H14)6]·20.5H2O (Th6hedta), [Th(C9O6NH12)(H2O)(NO3)]·1.5H2O (Th(ntp)), [Th2Al8(OH)14(H2O)12(C6O5NH8)4](NO3)6·17.5H2O (Th2Al8heidi), (C4N2H12) [Th2Fe2(OH)2(H2O)2(C6O7H4)2(C6O7H5)2]·6H2O (Th2Fe2cit), (C4N2H12) [ThFe2O(H2O)3(C11O9N2H13)2]·6H2O (ThFe2dhpta). Additional chemical characterization by infrared spectroscopy
and thermogravimetric analysis provides information on the chelation
by the organic ligands and thermal stability. These molecular complexes
can be utilized to understand aqueous speciation in mixed-metal solutions
and also provide information regarding contaminant adsorption on iron(III)
and aluminum(III) oxide surfaces.
