Figure 2
Hydrogen-bonded dimers in the structure of (II). These diagrams represent the extremes in which (a) Orient-A mol­ecules hydrogen bond to other Orient-A mol­ecules and (b) Orient-B mol­ecules hydrogen bond to other Orient-B mol­ecules. The most frequent real situation is probably a combination of the two. Indicated on the diagrams are the N—H⋯O (N1A—H1A⋯O2), C—H⋯O (C2—H2⋯O2) and C—H⋯π inter­actions for both types of hydrogen-bonded dimer. Mol­ecules (i) and (ii) are at the symmetry positions (x, y, z) and (−x + 2, −y, −z + 1), respectively.
