Lithiophorite, LiAl2(Mn4+2Mn3+)O6(OH)6, has a structure that contains alternating sheets of (Al,Li)(OH)6 octahedra and sheets of (Mn3+,Mn4+)O6 octahedra. The Al,Li sheet chemistry has an ideal ratio of Al:Li of 1:2, but may vary with charge balance being maintained by the Mn oxidation state. Sheets are held together by hydrogen bonding. Lithiophorite occurs in oxidized zones of Mn ore deposits, acidic soils, and low-temperature hydrothermal environments. Lithiophorite has been identified in nodules from Hawaiian soils.
