A migration of Mn3+ ions into previously unoccupied octahedral holes, while the oxygen and the phosphorus sites remain virtually unchanged, takes place in the course of the reaction of MnPO4 . H2O with LiNO3 to give the title compound (see polyhedral representation right: Li atoms as open circles. MnO6 octahedra and PO4 tetrahedra, H atoms omitted). These crystal-chemical effects are surprising. but such topotactic reactions are also of interest for the preparation of novel materials, for example for batteries and ionic conductors.
