Views of (a) the C—H⋯π and π–π stacking interactions between the one-dimensional chains, and (b) the three-dimensional architecture in (II). N—H⋯O hydrogen bonds are shown by dashed lines. One of the disordered conformations of each 2-TPC ring and H atoms in (b) have been omitted for clarity. Generic atoms labels without symmetry codes have been used. |
