Porous layered and open-framework mixed-valence copper tellurites

Novel porous layered and open-framework copper tellurites were obtained by CVT and hydrothermal methods. 1 demonstrates layered topology with pores (1×0.65 nm), whereas 2 has open-framework structural architecture with two-dimensional system of channels. Channels in open-framework of 3 are occupied by Tl+ cations.299
