Figure 8
Single-crystal X-ray structures at 290 K, highlighting the 2D halogen-bonded sheets, layers and TE axes for (a) and (b) diimine-I, and (c) and (d) diimine-Br. Type-II halogen⋯halogen bonds are shown with yellow dashed lines, type-I bonds are shown with blue dashed lines and C—H⋯X bonds are shown with green dashed lines. |
