This invention refers to a microporous crystalline material of zeolitic nature that has, in its calcined state and in the absence of defects in its crystalline matrix manifested by the presence of silanols, the empirical formula x(M1/nXO2):yYO2:gGeO2:(1-g)SiO2 in which M is selected between H+, at least one inorganic cation of charge +n, and a mixture of both, X is at least one chemical element of oxidation state +3, Y is at least one chemical element with oxidation state +4 different from Si, x takes a value between 0 and 0.2, both included, y takes a value between 0 and 0.1, both included, g takes a value between 0 and 0.5, both included that has been denoted ITQ-55, a method for its preparation and its use.
A microporous crystalline material of zeolitic nature having, in calcined state and in absence of defects in its crystalline matrix manifested by the presence of silanols, the empiric formula
A microporous crystalline material of zeolitic nature having a framework of tetrahedral (T) atoms connected by bridging atoms, wherein the tetrahedral atom is defined by connecting the nearest T atoms in the manner described in the following Table:
