摘要：

The crystal structure of La2LiSbO6 has been refined by neutron diffraction at 295 K. This compound adopts a distorted perovskite structure with an ordered distribution of Li and Sb atoms in B-sites and the La atoms are located in A-sites. The tilting of (Sb, Li)O6 octahedra is responsible of the irregular coordination in the LaO8 polyhedra. The bond valence calculations for metal atoms are in agreement with the experimental bond distances.
