Figure 2 A portion of the crystal packing of (I) showing the C—H⋯O hydrogen bonds (dashed lines) and I⋯O halogen bonding (dotted lines) [symmetry codes: (i) −x + , y + , −z + ; (ii) −x + 1, −y + 1, −z + 2; (iii) −x + 2, −y + 1, −z + 2]. H atoms not involved in hydrogen bonding are omitted for clarity. |
