Packing diagram of (I), showing a projection down [100]. The shaded A, B and C regions correspond to different hydrogen-bonding regimes, as discussed in the Comment. Inset: the centrosymmetric diamide R22(8) dimer present in structures A, D, E, H, I and K. [Symmetry codes: (i) x + 1, y, z; (ii) x − , y, −z + .] |
