Figure 2 Intermolecular contacts, viewed along [0 0 − 1]. For clarity, only hydrogen atoms participating in X—H⋯Y contacts are depicted. Blue dashed lines indicate classical hydrogen bonds, green dashed lines C–H⋯O contacts and yellow dashed lines C–H⋯Cl contacts. [Symmetry codes: (i) −x + , y + , z; (ii) −x + 1, y, −z + ; (iii) −x + , y − , z; (iv) x + , y − , −z + ]. |
