Thorium oxalate is the inorganic compound with the formula Th(C2O4)2(H2O)4. It is a white insoluble solid prepared by the reaction of thorium(IV) salts with an oxalic acid. The material is a coordination polymer. Each Th(IV) center is bound to 10 oxygen centers: eight provided by the bridging oxalates and two by a pair of aquo ligands. Two additional water of hydration are observed in the lattice.
