Structure description of ITQ-22. a,Building unit used to describe the crystal
structure with the corresponding atom numbering.Notice that with the exception of the
bridge T atom (T13),all other T atoms form part of this unit.The crystallographic mirror
plane passes through the inner 4MR (red:T atoms,green:oxygen atoms).b,Upper view of
zeolite ITQ-22 showing the bridge T13 atoms (blue).c,Three-dimensional structure model
of ITQ-22 zeolite showing the 8MR and
