Described herein are zeolite microporous crystalline materials comprising, in the heated state and in the absence of defects in its crystalline framework manifested by the presence of silanols, the empirical formula: x(M1/nXO2):yYO2:SiO2, wherein M is selected from H+, an inorganic cation of charge +n, and mixtures thereof, X is at least one chemical element having an oxidation state of +3, Y is at least one second chemical element other than Si having an oxidation state +4, x has a value between 0 and about 0.3, y has a value between 0 and about 0.1, and wherein the synthesized material has an X-ray diffraction pattern having at least values of angle 2theta (degrees) and relative intensities (I/I0) described. Process of making the microporous crystalline materials are also disclosed.
