The measurements of the magnetic properties in MUV-3-mimb, MUV-3-eimb, ZIF-67-mimb, ZIF-67-eimb and ZIF-67-eimi indicate the presence of strong antiferromagnetic metal-metal interactions between the M(II), as also observed in MUV-3. The presence of a single maximum in the magnetic measurements suggests a single phase transition, related to the presence of only one crystalline phase (Figure -S6), discarding the combination of two different phases or pure ligand domains. Moreover, the Neél temperatures (TN) for the mixedligand ZIFs (13.9-17.8 K) are close to the pure ligand SOD materials (17.2-20.6 K), in contrast to the TN found for dia and qtz topologies (TN = 32.2 and 35.9 K, respectively, see S2.3 section).
