As the metal is not changing among the ZIFs, one can expect that we underestimate the experimental value, but this underestimation is equal for all ZIFs. We analyze the heat capacity of 200 hypothetical ZIF structures assembled using four unique linkers and 50 topologies. Figure shows the heat capacity of the ZIFs. We observe a large dependence of the heat capacity on the linker functionalization (dots with different colors) and a very small influence by the framework topology (dots with the same color)
