The most straightforward way of matching an adsorbent from the NIST-ISODB to a MOF crystal structure in the CSD is by conventional name of the MOF, i.e., when any of the synonyms related to a NIST-ISODB's adsorbent matches with any synonym on the CSD Figure : Matching MOF crystal structures from the CSD to adsorbents in the NIST-ISODB: First match by conventional name. The remaining three approaches attempt a match by reference to a common published article that reported both the crystal structure(s) as well as the adsorption isotherm(s). side.
