eight-coordinate cation, which is similar to those of 2, 8–13. A novel lanthanum complex [H7O3][LaL2] (14) has been prepared by the treatment of La2O3 with an excess of aqueous 1,2-benzenedisulfonic acid and by treatment of 3 with perfluoroadipic acid in water. The complex anion forms polymeric chains with eight-coordinate lanthanum ions and μ-η2(O,O′):η2(O″,O″′)-disulfonate groups. Two oxygen atoms
