Abstract: The crystal structure of lithium manganese vanadate, LiMnVO₄, is characterized by chains of edge-sharing MnO₆ octahedra, bridged by pairs of edge-sharing LiO₄ and VO₄ tetrahedra. Cation-cation repulsions displace the V and Li ions from the tetrahedral centres and deform the tetrahedra further by shortening the mutually shared O-O edges. The smallest r.m.s. atomic displacements in thermal motion for Li and V are parallel to the shortest LiV vector with maximum vibrational motion normal to that direction. Cation-cation interactions between the Li and V tetrahedral sites play an important role.
