Abstract
A novel synthetic crystalline molecular sieve material, designated boron ITQ-21, is provided. The boron ITQ-21 can be synthesized using an N,N-diethyl-5,8-dimethyl-2-azonium bicyclo [3.2.2] nonane cation as a structure directing agent. The boron ITQ-21 may be used in organic compound conversion reactions and/or sorptive processes.
