(a) Part of the crystal structure of isomer (V) showing the formation of a chain of rings along [001] generated by one N—H⋯O hydrogen bond and two C—H⋯O hydrogen bonds. For the sake of clarity, the H atoms not involved in the motifs shown have been omitted. The atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions (x, 1 − y, − $[1\over2]$ + z) and (x, 1 − y, $[1\over2]$ + z), respectively. (b). Part of the crystal structure of isomer (V) showing the formation of a C(12) chain along [10 $[\overline 1]$ ] generated by a single C—H⋯O hydrogen bond. For the sake of clarity, the H atoms not involved in the motif shown have been omitted. The atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions (− $[1\over2]$ + x, $[1\over2]$ − y, $[1\over2]$ + z) and ( $[1\over2]$ + x, $[1\over2]$ − y, − $[1\over2]$ + z), respectively. (c) Part of the crystal structure of isomer (V) showing the formation of a C(11) chain along [11 $[\overline2]$ ] generated by a two-centre iodo⋯nitro interaction. For the sake of clarity, all of the H atoms have been omitted. The atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions (− $[1\over2]$ + x, − $[1\over2]$ + y, 1 + z) and ( $[1\over2]$ + x, $[1\over2]$ + y, −1 + z), respectively. (d) A stereoview of part of the crystal structure of isomer (V) showing the formation of a π-stacked chain along [110]. For the sake of clarity, all of the H atoms have been omitted.
