Figure 3
Part of the crystal structure of the title complex showing the arrangement of N—H⋯N hydrogen bonds. The proximity between π systems is reflected in the intermolecular C4⋯C4 separations, as measured using Mercury (Macrae et al., 2020; thin red lines): C4⋯C4i = 3.632 Å, and C4i⋯C4ii = 3.414 Å [symmetry codes: (i) 1 − x, 2 − y, −z; (ii) −1 + x, y, z]. The strongest intermolecular hydrogen bond (Table 2, entry 2) is represented by blue dotted lines. |
