Crystal structure of the oF244 crystal. Ideal structure model of the oF244 crystal constructed with hard PBPs. (A) View along the z axis and (B) y axis of the orthorhombic unit cell. Dashed lines indicate different orientations and layers of the 10-fold symmetric column (C) within the unit cell. Dark-green PBPs (120 particles in the unit cell) represent highly ordered layers of the crystal. Yellow PBPs (40 particles) represent weakly ordered layers of the crystal. PBPs existing between the 2 layers (84 particles) are colored in light green. The configuration of the dark-green and the light-green PBPs is well defined in the unit cell, while the configuration of yellow PBPs cannot be determined unambiguously due to their diffusive motion. (D) To determine the most probable number of PBPs in the weakly ordered region, we compared packing density at constant pressure (P* = 17.2) as a function of the number of the weakly ordered PBPs in the unit cell. (E) The unit cell with 40 weakly ordered PBPs has the highest packing density, suggesting it corresponds to the most stable structure.
