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⋯H11A^iv = 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 + $[{1\over 2}]$ .
