Figure 11
The steric circumstance of the nitro group in (IV). Only parts of the complexes are shown for clarity. The C—H⋯O hydrogen bonds are shown as blue dashed lines, O4⋯H11Aiv = 2.41 Å. The green dashed lines indicate the other O⋯H contacts, O4⋯H16iii = 2.69 Å. Symmetry codes: (i) x, −y + [{1\over 2}], z; (ii) −x + [{3\over 2}], −y, z + [{1\over 2}]; (iii) x + [{1\over 2}], y, −z + [{3\over 2}]; (iv) −x + [{3\over 2}], y − [{1\over 2}], z + [{1\over 2}].
