摘要： The present invention relates to a process for the preparation of organic-inorganic hybrid silicates and metal-silicates of the ECS type which uses as starting material the corresponding disilanes: said process is characterized by the presence of boric acid in the reagent mixture. With the process of the invention, ECS silicates and metal-silicates are obtained, characterized by an X-Ray diffractogram with reflections exclusively at angular values higher than 4.0° of 2Θ, and characterized by an ordered structure which contains: —structural units having formula (a), wherein R is an organic group: —boron—one or more elements T, different from boron, selected from groups IIIB, NB, VB, and transition metals, with a molar ratio Si/(Si+T) in said structure greater than 0.3 and lower than 1, wherein Si is the silicon contained in the structural unit having formula (a). The silicates and metal-silicates so obtained, containing both boron and at least one element T, are new. The process also allows new crystalline phases called ECS-13 and ECS-14 to be prepared.
