The two-dimensional sheet in (II), constructed by hydrogen bonds (orange dashed lines in the electronic version of the paper) and π–π stacking interactions (indigo dashed lines). H atoms not involved in C—H⋯Cl hydrogen bonds have been omitted for clarity. [Symmetry codes: (i) x + 1, −y + , z + ; (ii) x − 1, −y + , z − ; (iii) x − 1, y, z − 1.] |
