LiMn₂O₄: a spinel-related low-temperature modification

Abstract: Single-crystal synchrotron X-ray diffraction at 297  K revealed the spinel-related low-temperature orthorhombic form of black octahedrally shaped single crystals of lithium dimanganate, LiMn₂O₄, grown by the flux method. Three of five MnO₆ octahedra show typical Jahn-Teller distortions associated with Mn^III states. The bond valence sums indicate that these three sites are enriched with Mn^III and the other two with Mn^IV, though the charge distribution among these sites is still partially disordered.
