For the four different low temperature phases, the obvious question is how the phase behaviour differs with changing σ ang . Although the RDFs at higher values of σ ang suggest that the same phase persists from σ ang = 0.7 -1.0, on inspection of the structures, the cages orientations are disordered when σ ang ≥ 0.8 (Fig. ), likely due to the large values of σ ang and σ tor leading to less strongly directional interactions towards the facets. This means that although the phase behaviour looks similar, we are hesitant to call this the same phase and instead suggest that phases at higher σ ang behave more like plastic crystals, much like in the case of high values of σ ang for the window-to-window simulations. For the four orientationally ordered phases between σ ang = 0.2 -0.7, when looking down one of the high symmetry directions, each cage is surrounded by a hexagonal arrangement of cages. Interestingly, the angle of the hexagonal arrangement around the central cage compared to the orientation of the central cage changes as a function of σ ang , Fig. . This suggests that the arrangement of the cages can be tuned almost linearly as a function of the patch width. On a molecular level, the manipulation of σ ang may be achieved by changing the chemical functionality of the vertices or by using directional solvents. Bulkier groups on the vertices are likely to result in smaller values of σ ang . The bulkier the group, the greater the energetic penalty for neighbouring cages to be unaligned from a central position-a measure of the patch width-due to repulsive steric interactions. Similarly, solvents can be used to obtain more directional interactions, for example through hydrogen bonding between the pores, and therefore smaller values of σ ang .
