Two cluster-oxalate frameworks (denoted as SCU-62 and SCU-65) were prepared under solvent-free conditions. They contain extra-large 16-ring channels constructed from regular Mn6(SO4)6 double six-ring units (D6Rs) and lacunary In5(HPO4)6 D6Rs, respectively. Notably, SCU-65 remains stable in both boiling water and aqueous solutions with a pH range of 3-12. It has a proton conductivity of 5.5 × 10-5 S cm-1 at 85 °C under 95% relative humidity.
