SU‐16: A Three‐Dimensional Open‐Framework Borogermanate with a Novel Zeolite Topology

Abstract

A new secondary building unit with edge-sharing 3-rings of BO4 and GeO4 tetrahedra (shown in the picture in turquoise and yellow, respectively) forms the basis of the framework of SU-16, a borogermanate with zeolite topology. SU-16 has three-dimensional intersecting 12-ring and 8-ring channels. In particular the unusual elliptical 12-ring channels may make this zeolite structure interesting for shape selectivity.
