Figure 8
(a) Plot showing the three mol­ecules with the strongest inter­molecular inter­action energy to the central 4PYPY mol­ecule, shown with the Hirshfeld surface, in cocrystal DNIB·4PYPY. The halogen bonded mol­ecule is shown in red and labelled XB, π-stacked DNIB shown green and labelled PSCT, and the head-to-tail π-stacked 4PYPY shown in blue labelled PSPY. (b) Plot showing the three mol­ecules with the strongest inter­molecular inter­action energy to the central DNIB mol­ecule in cocrystal DNIB·4PYPY. Note that colours in (b) are not related to colours in (a). The turquoise mol­ecule labelled PSDN corresponds to an offset π-stacked DNIB mol­ecule.
