The present invention refers to a crystalline material that does not contain fluorides, with a composition in a roasted state corresponding to that of the material called ITQ-17 and that has a composition on an anhydrous base and in terms of oxide moles upon being synthesized, unroasted, represented by:

xX2O3:(1-z)YO2:zGeO2:r/nRnO

wherein:

    • X is at least one trivalent element,
    • Y is one or more tetravalent elements other than germanium,
    • R is an organic structure directing compound, preferably the cation 1-methyl-4-aza,1-azoniumbicyclo[2.2.2]octane (DABMe+) or the cation 1,4-bis[N-(4-aza,1-azoniumbicyclo[2.2.2]octane)methyl]benzene (d-DABBz)+2
    • x varies between 0 and 0.02,
    • z is comprised between 0.02 and 0.67,
    • r varies between 0.01 and 0.5, and
    • n is 1 or 2.
  • It also refers to a process for synthesizing said material, as well as to the material obtained by said process and subjected to a step of post-synthesis to eliminate the organic component from its structure.
