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.
