This patent describes a synthetic porous crystalline material being characterized by (1) an X-ray diffraction pattern exhibiting values substantially as set forth in TABLE 1 of the specification and (2) a composition comprising silica and alumina in the relationship (0.1-2)Al/sub 2/O/sub 3/:(100)SiO/sub 2/. The crystalline material of claim 1 in the as-synthesized form having a composition, on an anhydrous basis and in terms of moles of oxides per 100 moles of silica, expressed by the formula: (0.1-2.0)R/sub 2/O:(0.02-1.0)M/sub 2/n/O:(0.1-2)Al/sub 2/O/sub 3/(100) SiO/sub 2/ wherein M is an alkali or alkaline earth metal cation, n is the valence of M, and R is a methyltropinium cation.
