Figure 4
The arrangement of the ions of polymorph (Ib) in the unit cell, viewed along the b axis. The C—H⋯O interactions and O⋯Cl contacts are represented by dashed lines, and Cl—O⋯π and π–π interactions by dotted lines. H atoms not involved in the interactions have been omitted. [Symmetry codes: (i) x − 1, y, z; (iv) 1 + x, y, z; (v) 1 − x, y − , − z.] |
