(E)-2,4-Di-bromo-6-(hydrazinylidenemeth-yl)phenol

摘要

The title compound, C7H6Br2N2O, was obtained from a condensation reaction of 3,5-di-bromo-2-hy-droxy-benzaldehyde and hydrazine hydrate. The mol-ecule is approximately planar, the largest deviation from the mean plane through all of the non-H atoms being 0.053?(1)??. The mol-ecular conformation is stabilized by an intra-molecular O—H?N hydrogen bond, generating an?S(6) ring motif. In the crystal, inter-molecular N—H?Br and N—H?O hydrogen bonds link the mol-ecules, forming chains parallel to the?b?axis. Mol-ecules are further linked by?π–π?stacking inter-actions, with centroid–centroid distances of 3.925?(3)–3.926?(3)??, forming a three-dimensional network.
