Figure 4
Crystal packing of (1) in a view along [100]. Intra­molecular N—H⋯O hydrogen bonds are shown as light-blue and inter­molecular C—H⋯O hydrogen bonds as dark-blue dashed lines. Dashed red lines denote contacts C=O⋯Cg1 and C=O⋯Cg7 (slippage 1.676 Å for both), and dashed light-green lines Cg1⋯Cg3 and Cg7⋯Cg9 contacts. Cg3, Cg9, Cg1 and Cg7 correspond to the ring centroids C6A–C9A/C9AA/C5AA, C6B–C9B/C9BA/C5BA, N5A/C4AA/N10A/C10A/C9AA/C5AA and N5B/C4BA/N10B/C10B/C9BA/C5BA, respectively. For clarity, only H atoms H5A, H8A, H5B and H8B are shown.
