Framework Density

The complex LTN-type zeolite framework is described as consisting of two interpenetrating parts in order to understand the connectivities of their underlying nets. Both parts are homeomorphic to diamond-type tetrahedral frameworks, arranged in principle in the same manner as the two interpenetrating frameworks in cuprite, Cu2O. However, in cuprite the two frameworks are identical, while in the LTN-type framework one is made up of two kinds of truncated octahedra (toc units) and can be described as one half of the sodalite-type framework (SOD). The other consists of large cages, so-called truncated cubo-octahedra (grc units) connected by hexagonal prisms (double six-rings) and corresponds to one half of the KFI-type framework. Neither of the sub-frameworks has so far been observed in any other zeolite topology. The two sub-frameworks of SOD and KFI types in the interpenetrating LTN-type framework are models for very open interrupted frameworks, which possibly could be synthesized separately in a pure form. Their framework density would be 7.6 T atoms per 1000 Å3 if they could be prepared as aluminosilicates.

Common Application

AbstractUsing an analogy with three-connected networks of hyperbolically-curved single sheets, a method for construction of tetrahedral frameworks corresponding to interconnected, double-sheeted relatives of these is presented. The analogy is founded upon common application of the bond switch mechanism to the structures. Considering the simplest such examples, models of the frameworks sheathing the triply-periodic minimal surfaces P, D and G are given. For each of these cases the systems of tunnels and cavities thus formed are significantly larger than those for the established zeolite structures.
