Figure 4
The supramolecular structure of (IB), showing (a) the chain viewed parallel to the b axis and (b) the packing viewed parallel to the a axis. (Key: 1 = Cg1, 2 = Cg2, 3 = Cg3 and 4 = Cg4.) Blue dashed lines represent π–π interactions and green dashed lines represent C—H⋯Cl hydrogen bonds. All H atoms, except those involved in hydrogen-bonding interactions, have been omitted for clarity. [Symmetry codes: (i) x − 1, −y + , z − ; (ii) x + 1, −y + , z + ; (iii) −x + 1, y + , −z + ; (iv) −x + 2, y + , −z + .] |
