Comparison of the steric circumstances of the nitro group in (I) and (II). Dashed lines in blue indicate O(nitro)⋯H short contacts shorter than 2.5 Å. Only part of the diamine ligands are shown for clarity. Symmetry codes for (I): (v) −x + , −y + , −z; (ix) x, −y, z − . For (II): (ii) −x + 1, −y + 1, −z + 1; (v) x − , −y + , z + . |
