Representation of some molecules of 3-bromo-2-(phenylsulfanyl)benzo[b]selenophene (1) viewed approximately down the c axis of the unit cell. The red dashed lines represent C—H⋯π interactions involving the H5 atom of the benzo[b]thiopehene ring with an adjacent phenylsulfanyl group; the purple dashed lines represent π–π stacking interactions between adjacent benzo[b]thiopehene rings. Displacement ellipsoids are drawn at the 50% probability level. The hydrogen atoms, except for H4, are omitted for clarity. Red and purple spheres represent the centroids of the respective organic groups. |
