A porous crystalline material (ITQ-21) which in its calcined form has the
chemical composition
X.sub.2 O.sub.3 :nYO.sub.2 :mZO.sub.2
wherein (n+m) is at least 5, X is a trivalent element, Z is Ge, Y is at
least one tetravalent element other than Ge, and the ratio is m/(n+m) is
0.0 to 0.5, and displays the X-ray diffraction values given in Table 1,
and a method of preparation of the material in the presence of fluoride
ions and using N(16)-methylsparteinium as structure director agent; the
material being useful in its acid form and in bifunctional catalyst form
in processes of catalytic cracking, hydro-cracking and alkylation of
aromatics.
