We start with the method of Shearer et al. In their calculation the residual mass is assumed to consist of only metal oxide (in line with our own assumptions regarding TGA). The TGA curve is then normalised to have the residue plateau at 100 %. In a next step the ideal residue mass (Wideal,plat) is calculated by dividing the MOF molar mass by the metal oxide molar mass, taking into account the expected MOF metal stoichiometry and its composition at the temperature chosen for comparison (e.g. taking into account hydroxylation). The theoretical total mass Wtheo for this MOF composition is then calculated by (Wideal,plat -100)/NLideal, where NLideal is the theoretical number of linkers per mole MOF. The experimental value for the number of linkers per cluster can then be found as
