Structure orienting role of germanium in zeolite synthesis

This paper deals with the synthesis results obtained from pure silica and (Si, Ge) systems in presence of hexamethonium cations, Kryptofix2,2,2 and 5-azoniaspiro4,5decane derivative cations as organic structure directing agents (OSDA) in hydroxide or fluoride media. The obtained new materials Mu-31, IM-9, IM-10 (UOZ), IM-11(LTA), IM-12 (UTL) all contain D4MR units, confirming the orienting effect of the germanium and/or the fluoride anions towards this small cage. Surprisingly, the extra-large pore IM-12 zeolite could not be obtained in the fluoride medium.
