The invention concerns a crystalline solid, designated IM-10, 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, in accordance with the formula XO<SUB>2</SUB>:mYO<SUB>2</SUB>:pZ<SUB>2</SUB>O<SUB>3</SUB>:qR<SUB>2/n</SUB>O:sF, in which R represents one or more cation(s) with valency n, X represents one or more tetravalent element(s) other than germanium, Y represents germanium, Z represents at least one trivalent element and F is fluorine.
