Figure 2 . Part of crystal structure of (I) showing molecular chains running along the b-axis and interconnected through the Cl—Cl contacts. Hydrogen bonds and short Cl—Cl contacts are shown as dashed lines. H atoms not involved in hydrogen bonding were omitted. Symmetry codes: (i) x, 1+y, z; (ii)−x, 1-y, 1-z. |
