The reaction of Bi4Ti3O12-x with lithium iodide under an atmosphere of iodine at 400°C was found to afford a novel intercalation compound Lil3Bi4Ti3O11. The brownish red bismuth titanate is monoclinic with the lattice parameters of a=5.7417(2), b=5.4016(2), c=36.787(1) Å and ß=88.93(1) deg. The pathway to the new intercalation compound is proposed on the basis of X-ray, XPS, SEM and compositional observations.
