Literature reports typically try to obtain a value for 'missing linkers'. Since there is no way to account for the simultaneous presence of missing metal nodes, we prefer to report an experimental value for the MOF stoichiometry, given by nlinker/nM, which can then be compared to the expected value. Assuming that at high temperatures and under an oxidative atmosphere such as air only the metal oxide MxOy remains, we start from the mass (m) of the residue of the TGA
