Using guest adsorption as a stimulus to access the metastable cp/lp coexistence regions in CoBDP. a Free energy and c pressure equations of state at loadings of 0, 2, and 4 methane molecules per conventional unit cell, with b indication of the metastable (\({n}_{{\rm{cp}}}\),\({n}_{{\rm{lp}}}\)) phase coexistence regions as a function of the volume for the empty framework for an 8 × 2 × 8 mesocell of CoBDP at 300 K. The different (meta)stable states and transition states are indicated on the free energy equations of state with (open) circles and crosses, respectively
