Crystalline molecular sieves having three-dimensional microporous frame work structures of MnO 2 , AlO 2 , SiO 2 and PO 2 tetrahedral oxide units are disclosed. These molecular sieves have an empirical chemical composition on an anhydrous basis expressed by the formula: n n mR: (Mn.sub.w Al.sub.x P.sub.y Si.sub.z)O.sub.2 n n 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 w Al x P y Si z )O 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. |
