Abstract
The present disclosure is directed to novel crystalline germanosilicate compositions and methods of producing the same. In particular, the crystalline germanosilicate compositions are extra-large-pore compositions, designated CIT-13 possessing 10- and 14-membered rings. The disclosure describes methods of preparing these compositions using substituted benzyl-imidazolium organic structure-directing agents (OSDAs). Also disclosed are methods of using these crystalline compositions.
