Crystal Engineering: Toward Intersecting Channels from a Neutral Network with a bcu-Type Topology

In rare form: Although the structure of the body‐centered cubic (bcu) net is commonly found in textbooks, its eight‐connected topology is extremely rare in metal–organic frameworks owing to severe geometric requirements. The first example of a highly porous, neutral bcu‐type framework (see picture) assembled from a unique eight‐connected tricopper cluster and a 5‐(4‐pyridyl)tetrazolate ligand as linker is reported.
