Synthesis and Characterisation of Mu-26 a Fluorinated All-Silica Zeolite with the STF Framework Topology: Evidence for a Triclinic Symmetry

X-ray powder diffraction pattern analysis and multinuclear solid state NMR studies performed on the as-synthesised Mu-26 solid, a fluorinated all-silica zeolite with the STF framework topology, have revealed unambiguously a triclinic unit cell and space group P1 for this material.
