Abstract
Crystalline molecular sieves having three-dimensional microporous frame work structures of MnO.sub.2, AlO.sub.2, SiO.sub.2 and PO.sub.2 tetrahedral oxide units are disclosed. These molecular sieves have an empirical chemical composition on an anhydrous basis expressed by the formula: mR: (Mn.sub.w Al.sub.x P.sub.y Si.sub.z)O.sub.2 wherein 'R' represents at least one organic templating agent present in the intracrystalline pore system; 'm' represents the molar amount of 'R' present per mole of (Mn.sub.w Al.sub.x P.sub.y Si.sub.z)O.sub.2 ; and 'w', 'x', 'y' and 'z' represent the mole fractions of manganese, aluminum, phosphorus and silicon, respectively, present as tetrahedral oxides. Their use as adsorbents, catalysts, etc. is also disclosed.
