    201943&ensp·&enspAn association energy of 2225 kJ/mol is typical of chargeinduced dipole interactions, and so there is interest in the use of charged linkers and metals. The metal–hydrogen bond strength is diminished in MOFs, probably due to charge diffusion, so 2+ and 3+ metal ions are being studied to strengthen this interaction even further.
