Figure 3
Halogen and hydrogen bonding in 1 (atoms are shown as spheres of arbitrary size). Dashed lines represent hydrogen and halogen bonds. Only those atoms involved in halogen or hydrogen bonding are labeled. Symmetry codes: Br1A = −x, 1 − y, −z; Br1B = x, y + 1 z; N12B = −x, 2 − y, −z; I15C = 1 − x, y, z − 1. |
