Neutron diffraction powder profile analysis has been used to determine the structure of Li2FeV3O8. The compound is prepared from FeV3O8, which has the VO2(B) structure type, by a lithium insertion reaction employing n-BuLi. Only minimal distortion of the host lattice occurs on Li insertion. The Li ions occupy five coordinate square pyramidal sites with an average LiO bond distance of 2.04 Å. These five coordinate sites occur commonly in the capped perovskite cavities of crystallographic shear structures based on ReO3.
