The polaron-ordered structure of La{sub 1-x}Sr{sub x}MnO{sub 3} (x{congruent}1/8) has been reinvestigated to verify the previously proposed models. We found satellite reflections on the (0,k,l){sub ortho} and (1,k,l){sub ortho} reciprocal planes. It has been shown that neither of the previously proposed models is completely consistent with the observed results. Based on theoretical consideration of interhole interactions in a perovskite-based structure, the experimental results are analyzed. A polaron ordered structure with unit cell size of ({radical}2x{radical}2x4){sub cubic} has been proposed which is substantially consistent with the observed neutron-scattering pattern.
