* Disordered Type Material
The Type Material of this Framework Type is disordered. An ordered framwork structure is given here to facilitate the discription, but no bulk material with this stucture is presently known. A brief description of the disorder is given below. For more details see the original publication.
The asterisk in the code indicates that ZSM-48 is disordered. The most representative polymorph 6 (Lobo and van Koningsveld) has been selected as the Framework Type.
