Attempts to create a porous molecular crystal by removing solvent molecules from a solvate usually lead the host to reorganize into a non-porous close-packed structure. The 'virtual porosity' of such an organic cage crystal has now been trapped by introducing a judiciously chosen co-crystal former that prevents rearrangement of the host lattice.
