Figure 5
Hirshfeld surfaces mapped over dnorm (−0.15 to 1.20 Å) for the P21/n polymorph reported in 2003 (Panja et al., 2003BB17; top) and the novel P21 polymorph (bottom). Arrows in the first case indicate regions where inter­molecular distances are shorter than van der Waals contacts, because of π–π inter­actions.
