Abstract : The unit cell of the compound Bi2Ti4O11 is facecentered monoclinic and contains 4 formula units. Its space group is C 2/c with all atoms in general positions, except for oxygen atoms lying on twofold axes. A phase transition is observed at 250C, and the structure of the high-temperature modification is discussed. The unit cell of a related structure, probably stablized by impurities, is also reported.
