Exceptional stability and high hydrogen uptake in hydrogen-bonded metal-organic cubes possessing ACO and AST zeolite-like topologies

A novel approach for targeting zeolite-like metal-organic frameworks (ZMOFs) that utilizes metal-organic cubes and are regarded as double four-membered rings (d4Rs) and are composite building units (BUs) in traditional inorganic zeolites are reported. The implimentation of the new method is demonstrated by two ZMOFs with ACO and AST zeolite-like topologies constructed from d4R BUs exclusively held together by hydrogen bonds.
