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: <?in-line-formulae description="In-line Formulae" end="lead"?>xX<SUB>2</SUB>O<SUB>3</SUB>:(1-z)YO<SUB>2</SUB>:zGeO<SUB>2</SUB>:r/nR<SUB>n</SUB>O<?in-line-formulae description="In-line Formulae" end="tail"?> 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<SUP>+</SUP>) or the cation 1,4-bis[N-(4-aza,1-azoniumbicyclo[2.2.2]octane)methyl]benzene (d-DABBz)<SUP>+2 </SUP> 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.
