Figure 4
Packing differences between (I)

and (II)

. Molecules of (I)

(thin bonds) are linked by C15—H15A⋯O2ⁱⁱ interactions, while molecules of (II)

(thick bonds) form C15—H15A⋯O1ⁱⁱ interactions. For clarity, O⋯I halogen bonding is shown only for (II)

. Interactions are indicated by dashed lines. [Symmetry codes: (i) −x + $[{1\over 2}]$ , y − $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (ii) x − $[{1\over 2}]$ , −y + $[{1\over 2}]$ , z − $[{1\over 2}]$ .]
