K6[Fe8.27(HPO3)12]: a new mixed-valence iron phosphite

F. Hamchaoui, V. Alonzo, H. Rebbah and E. Le Fur

Synopsis: The crystal structure of a mixed-valence iron phosphite has been solved from single-crystal X-ray diffraction data in the trigonal space group R\overline{3}m. The compound shows anionic [Fe3(HPO3)4]2- and [Fe(HPO3)2]- sheets stacked in a disordered manner along the c axis, with the K+ cations located in the inter­layer spaces.

Formula: K6[Fe8.27(HPO3)12]
