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 oxalic acid.^[1] 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 waters of hydration are observed in the lattice.^[2]
