Figure 8
(a) The Hirshfeld surface of (V) mapped over dnorm. Short and long contacts are indicated as red and blue spots, respectively. Contacts with distances approximately equal to the sum of the van der Waals radii are colored white. Hydroxyl and carbonyl groups on the anthrone ring contributed major short contacts. (b) π–π interactions (anthrone to anthrone and carbonyl to isoxazole ring) and σ–π interaction (C—H bond to carbonyl) are shown as orange–red spots with green dashed lines in the shape-index map. |
