A new class of hybrid super-supertetrahedral cluster and its assembly into a five-fold interpenetrating network

Abstract

We describe an entirely new type of tetrahedral cluster, representing a new level of structural hierarchy: a hybrid tetrahedron of supertetrahedra, formed by five T3 supertetrahedral clusters connected by bipyridyl linkers. Covalent assembly of these 37 Å super-supertetrahedra with smaller (10 Å) T3 clusters results in the formation of a two-dimensional covalent network which contains pores in the mesoporous range.
