ABSTRACT:
The invention relates to a crystallized solid, referred to by the name IM-12, which exhibits an x-ray diffraction diagram as provided below. Said solid exhibits a chemical composition that is expressed on an anhydrous base, in terms of oxide moles, by the formula XO2:m YO2:p Z2O3:q R2
O, where R represents one or more cation(s) of valence n, X represents one or more different tetravalent element(s) of germanium, Y represents germanium, and Z represents at least one trivalent element.
