摘要：

Lithium manganese oxide crystals with composition (Li0.91Mn0.09)Mn2O4 were synthesized by a flux method. The crystals have a structure closely related to that of the cubic spinel LiMn2O4, but 9% of the lithium ions in the tetrahedral 4a site are substituted by Mn2+ ions. This substitution lowers the average Mn oxidation state below 3.5+, resulting in a Jahn-Teller distortion of the MnO6 octahedron.
