Abstract: Various zeolites may be produced under hydrothermal synthesis conditions in the presence of a silicon atom source and a bis-pyridinium compound having a structure represented by formula (I). Q is an optionally substituted C1-C10 hydrocarbyl group and two Q may join to form a carbocyclic ring; n is an integer ranging from 0 to 5; m is an integer ranging from 0 to 5; n+m is greater than or equal to 1; and A is a spacer group containing 2 to about 10 atoms.
