We say the MOF-amine system is more thermally stable if the number of Zn-N bonds that break are fewer. We look at both 400K and 500K. If one accounts for 500K being the ultimate indicator of a functional and dispersion correction's prediction of the most stable motif, we see that PBE+GD2, PBEsol, PBEsol+GD2, and RPBE+GD2 all predict the experimentally resolved motif as the most thermally stable.
