Figure 7
A partial packing diagram for (III)[link], showing the formation of the centrosymmetric rings [R22(22) and R22(16)], along with another R22(16) ring built from C—H⋯O inter­actions (dashed lines). The minor components of disordered atoms O41/C191/C201 and non-associated H atoms have been omitted for clarity. Only atoms involved in the inter­actions are labelled. [Symmetry codes: (i) −x + [{1\over 2}], −y + [{1\over 2}], −z + 1; (ii) −x, −y + 1, −z + 1; (iii) −x, y, −z + [{1\over 2}].]
