Abstract

Lithium manganese oxide crystals with composition (Li(0.91)Mn(0.09))Mn(2)O(4) were synthesized by a flux method. The crystals have a structure closely related to that of the cubic spinel LiMn(2)O(4), but 9% of the lithium ions in the tetrahedral 4a site are substituted by Mn(2+) ions. This substitution lowers the average Mn oxidation state below 3.5+, resulting in a Jahn-Teller distortion of the MnO(6) octahedron.
