A crystalline solid designated IZM-3 is described 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 aSiO2:bYO2:cR:dF, in which Y represents at least one tetravalent element other than silicon, R represents at least one organic nitrogen-containing species, and F is fluorine, a, b, c and d respectively representing the number of moles of SiO2, YO2, R and F and a is in the range 0.1 to 1, b is in the range 0 to 0.9, c is in the range 0.01 to 0.5 and d is in the range 0 to 0.5.
