Solvent-induced generation of two magnesium-based metal–organic frameworks with doubly inter-penetrated ReO3 nets constructed from the same linkers but distinct inorganic nodes

• Solvent-induced variation of metal clusters in metal–organic frameworks
• Two magnesium-based MOFs with doubly interpenetrated ReO3 nets were synthesized.
• Two MOFs are constructed by identical BTB linker and distinct Mg-containing nodes.

Through changing the components of solvent, two Mg-based metal–organic frameworks were synthesized, which possess the same two-fold interpenetrated ReO3 net constructed by identical linkers, 4,4′,4″-benzene-1,3,5-triyl-tribenzoate, but distinct nodes, Mg2 and Mg6 units, respectively. Here, DMSO and water are key factors for forming hexanuclear clusters, while DMF and DMSO act as template reagents for constructing super-octahedral cavities.
