Crystal structure of cronstedtite-6T2, a non-MDO polytype
Original language description
The crystal structure of cronstedtite-6T2, a new polytype of the 1:1 layered silicate, was refined using a crystal from the occurrence in Pohled, Czech Republic. The space group is P31, lattice parameters a=5.4976(3), c=42.601(1) Å, Z=6, composition (Fe2+2.515 Fe3+0.485) (Si1.515 Fe3+0.485) O5 (OH)4, Robs = 4.13% for 3244 independent reflections. Positions of all atoms including hydrogens are referred, geometries of tetrahedra, octahedra, and interlayer hydrogen bonds are described. Cronstedtite-6T2 is a non-MDO polytype, since more than one kind of layer triplets can be found in the stacking sequence.
