N2 - A cerium-doped SrTiO 3 compound with the composition Sr 0.4 Ce 0.4 TiO 3 has been produced by conventional solid-state processing. The structure of this compound was analyzed by X-ray, electron, and neutron diffraction. While no superlattice can be observed via X-ray diffraction, both electron and neutron diffraction show evidence of a noncubic supercell caused by antiphase tilting of oxygen octahedra. The most likely space group is C 2/ c , corresponding to an a - b - b - tilt system. Octahedra are tilted by ~5° about the pseudo-cubic a -axis and ~1.5° about the pseudo-cubic b - and c -axes.
