Interaction between symmetry-related molecules. A primary molecule (orange) and the nearest symmetry-related molecules (blue) obtained by applying the symmetry operators of the space group of the crystal (P6522) to the primary molecule are shown, as well as lattice translations. Taken together, all these molecules form a network of interactions which is connected throughout the crystal in all three dimensions. The molecules interact through three interfaces, labelled 1, 2 and 3. Interface 2′ is related by crystallographic symmetry to interface 2. Of the three interfaces, interface 1 involves the most extensive interactions, with a buried suface area of 1569 Å2 (compared with 541 Å2 for interface 2 and 276 Å2 for interface 3; the buried surface areas were computed with the PDBePISA server). Considering the extensive interactions, interface 1 is likely to promote dimerization of the molecule, as is also suggested by the PDBePISA server. |
