Abstract

The title compound, C₁₉H₁₅BrN₂O, crystallizes with two similar mol-ecules in the asymmetric unit. The extended structure features dimers linked by pairs of N-H⋯O and C-H⋯O hydrogen bonds. The HNCNO moiety of the title compound shows delocalization over the N-C-N part, as evidenced by the similar C-N bond distances.

Keywords: amidine N-oxides; crystal structure; ligand synthesis.
