Abstract
The invention concerns a crystalline solid designated IZM-2, which has the X ray diffraction diagram given below. Said solid has a chemical composition expressed as the anhydrous base in terms of moles of oxides by the formula XO2:aY2O3:bM2/nO, in which X represents at least one tetravalent element, Y represents at least one trivalent element and M is at least one alkali metal and/or an alkaline-earth metal with valency n, a and b respectively representing the number of moles of Y2O3 and M2/nO; a is in the range 0 to 0.5 and b is in the range 0 to 1.
