| dc.description.abstract-en | Cs-ferriannite, ideally CsFe32+ (Fe3+Si3)O-10(OH)(2), was synthesized as euhedral crystals, starting from an oxide mix, at 550 degrees C and 0.1 GPa water pressure. Using 860 independent reflections, the crystal structure of its 1M polytype was refined in the C2/m space group with R equal to 5.5%. All octahedral positions as well as 23% tetrahedral positions are occupied by iron. Its octahedral sheet is geometrically homooctahedral with all octahedra the same in size. The tetrahedral and octahedral sheets are nearly undistorted. Cs-ferriannite is the 1M mica with the largest unit cell known to date: a = 5.487(1) Angstrom, b = 9.506(2) Angstrom, c = 10.826(6) Angstrom, beta = 99.83(3)degrees, Z = 2.
The mica appears to be a stable crystalline phase that may serve for fixation and storage of radioactive cesium isotopes in its interlayer. | en |
