The phase diagram of tetrahedral, patchy particles [1] exhibits the following solid phases: Diamond Crystal (DC), Body Centered Cubic (BCC) and Face Centered Cubic (FCC). The gas-liquid critical point becomes metastable with respect to the Diamond Crystal when the range of the interaction becomes short (roughly less than 15% of the diameter).
By contrast to isotropic models, the critical point has only a weak metastability with respect to the solid as the interaction range narrows (from left to right in the figure).
