Abstract

Four open-framework copper titanosilicates have been synthesized by hydrothermal techniques. The crystal structure of Phase 1 determined from single crystal X-ray data is closely similar to that reported for the titanosilicate ETS-4 with ca. one third TiO5 pyramids randomly replaced by CuO4 squares. Phase 2 also has the ETS-4 structure but all the TiO5 pyramids are replaced by CuO4 squares which are not randomly disordered. Phase 3 with the composition Na8CuTi3Si16O43 has the same structure as the mineral narsarsukite, a titanosilicate closely related to the microporous titanosilicate ETS-10. Narsarsukite and ETS-10 have the same straight single chains of TiO6 octahedra which are partially substituted by CuO4 squares in 3. Phase 4 with the composition K4CuTiSi8O21 contains CuO4 squares and TiO5 tetragonal pyramids that crosslink a new type of silicate double layer to form an open framework.
