Figure 5
(a) The electrostatic potential surface of polymorphs I (major component, atoms C6A–C11A) and Iⁱ and compound II, mapped over colour ranges −0.09 to 0.05, −0.07 to 0.05, and −0.09 to 0.06 au., respectively; (b) the Hirshfeld surface of polymorphs I and Iⁱ and compound II, mapped over d_norm in the colour ranges −0.16 to 1.37, −0.21 to 1.28, and −0.30 to 1.91 au., respectively.
