摘要：

New sodium iron orthophosphate NaFe42+Fe33+[PO4](6) was synthesized by the hydrothermal method. The crystal structure (sp. gr. P (1) over bar) was established by the heavy-atom method, with the exact chemical formula of the compound being unknown; Rhkl = 0.0492, R,,,hkl = 0.0544, S = 0.52. The new compound is anal0 ogous to iron phosphate Fe32+Fe43+ [Po-4](6) studied earlier. However, these two compounds differ in the Fe2+ and Fe3+ contents, because Na+ ions in the new compound are located at the centers of symmetry not occupied earlier.
