Abstract
Pure polymorph C (denoted ITQ-17) resulting from the intergrowth of zeolite Beta has been synthesized in the presence of Ge from a fluoride-free synth esis mixture; this shows that fluoride is not necessary to obtain structure s containing D4MR units that were believed to be stabilised by fluoride; on the other hand, the presence of Ge directs the synthesis towards the forma tion of pure polymorph C.
