The packing of the hydrogen-bonded dimers (dashed lines) in (IV). Shaded areas indicate the least-squares planes involved in π–π stacking interactions. Dichloromethane solvent molecules have been omitted for clarity and only those H atoms involved in hydrogen bonding are shown. [Symmetry codes: (i) 1 + x, y, z; (ii) 2 + x, y, z.] |
