The steric circumstance of the nitro group in (III). Only parts of the complex are shown for clarity. The C—H⋯O hydrogen bonds are shown as blue dashed lines, O4⋯H10Cvii = 2.53 Å. The green dashed lines indicate the other O⋯H contacts, O4⋯H19vi = 2.71 Å. Symmetry codes: (i) x, −y + , z; (ii) x, −y + , z + 1; (iii) x + , −y + , −z + ; (iv) x + , y, −z + ; (v) x + , −y + , −z + ; (vi) x − , −y + , −z + ; (vii) x − , y, − z. |
