Abstract

The isostructural metal-organic frameworks [{Zn₂(abtc)(dmf) ₂}₃] (1a), [{Cu₂(abtc)(dmf)₂} ₃] (2a), and [{Cu₂(abtc)}₃] (2b; H ₄abtc = 1,1′-azobenzene-3,3′,5,5′-tetracarboxylic acid) have high sorption capacities for H₂, N₂, CO ₂, and CH₄. Solid 2b, which has accessible metal sites (AMSs), has a higher H₂ adsorption capacity than 1a or 2a (see picture; T = 77 K), neither of which have AMSs, because of its lower molecular weight and greater isosteric heat of H₂ adsorption.
