Abstract
Bright-yellow single crystals of the title compound were synthesized as part of a project that explores the formation of earth-abundant transition-metal complexes of amidine oxides (AMOXs), to study their photophysical and redox properties. The HNCNO moiety of the compound shows double-bond delocalization over the N—C—N part, evident from the similar C—N bond distances.
The title compound, C19H15BrN2O, crystallizes with two similar molecules 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.
