Abstract
This invention relates to a crystalline composition having a three-dimensional microporous structure of MA.sub.2 units where A is sulfur or selenium and having the empirical formula expressed in molar ratios: xR:MA.sub.2.+-.0.2 :zH.sub.2 O where R represents at least one organic templating agent present in the intracrystalline pore system, x is the moles of R, z is the moles of water and M is germanium or tin. This invention also relates to a composition having the empirical formula expressed in molar ratios: xR:M.sub.1-y M'.sub.y A.sub.2.+-.0.2 :zH.sub.2 O, where M' is a metal such as cobalt, zinc, manganese, iron, nickel, copper, cadmium and gallium. This invention further relates to a method of preparing the crystalline composition.
