Figure 3
Part of the crystal structures of (a) (II)[link], (b) (IV)[link], (c) (V)[link] and (d) (III)[link], showing the inter­molecular π–π inter­actions (thin dashed lines) linking the mol­ecules of each of these compounds into stacks parallel to the shortest crystallographic axes, as well as the inter­stack O—H⋯O and halogen–halogen inter­actions (thick dashed lines). All H atoms not involved in these inter­actions have been omitted for clarity. The centroids of the benzene rings (Cg) are denoted by small spheres.
