Interaction energies in crystal structure of I. (a) A view of interactions between a central molecule of CECO2 in crystalline I, shown as its Hirshfeld surface, and 14 molecules that share the interaction surfaces with the central molecule. (b) Calculated energies (electrostatic, polarization, dispersion, repulsion, and total) of pairwise interactions in I between the central molecule and those indicated by respective colors. (c) Energy framework for pairwise electrostatic interaction energies in I. The cylinders link molecular centroids, and the cylinder thickness is proportional to the magnitude of the energies, such as those shown in (b). For clarity, the cylinders corresponding to energies <5 kJ mol−1 are not shown. (d) The pairwise dispersion energy framework in I. |
