^*The OMS density of MOFs was calculated based on the crystal information files.

^†The framework density was calculated from single-crystal X-ray data.

^‡Density of adsorbed C₂H₂ in bulk material.

^§Pressure of C₂H₂ at 295 K corresponding to the calculated density of adsorbed C₂H₂ in bulk material.

^||Data for FJI-H8 at 308 K.

^¶The value of C₂H₂ uptake by OMS is larger than the sum value maybe because of the interaction between open Mg(II) sites and acetylene molecules are so weak that open Mg(II) sites cannot be fully loaded.
