Figure 2 The packing arrangement of the title compound viewed down b axis. The dashed lines indicate C—H⋯O intermolecular interactions, which are results in (15) and (19) ring motifs. The hydrogen atoms not involved in the hydrogen bonding and phenylsulfonyl group have been excluded for clarity. Symmetry codes: (i) + x, 1-y, z; (ii) −1 + x, y, z; (iii). − + x, −y, z. |
