Graphical Abstract

Thumbnail image of graphical abstract

All square: Treatment of m-phenylenebis(β-diketones) with [Cu(NH3)4]2+ yields molecular squares rather than the expected hexagons. The squares react readily with guests such as C60 (see structure) and 4,4′-bipyridine. They are also effective for the storage of H2 gas, both at 77 K and at room temperature.
