Figure 9 C—H⋯O and C—H⋯π intermolecular interactions highlighting the packing features in (IV). Molecules labeled with a hash (#), asterisk (*) or double prime (′′) have the symmetry codes (−x, −y, −z + 2), (x, y + 1, z) and (−x + 1, −y + 1, −z), respectively, with Cg3 denoting the center of gravity of the C16–C21 aromatic ring.
