(E)-2,4-Di­bromo-6-(hydrazinylidenemeth­yl)phenol

The title compound, C7H6Br2N2O, was obtained from a condensation reaction of 3,5-di­bromo-2-hy­droxy­benzaldehyde and hydrazine hydrate. The mol­ecule is approximately planar, the largest deviation from the mean plane through all of the non-H atoms being 0.053 (1) A. The mol­ecular conformation is stabilized by an intra­molecular O—H⋯N hydrogen bond, generating an S(6) ring motif. In the crystal, inter­molecular N—H⋯Br and N—H⋯O hydrogen bonds link the mol­ecules, forming chains parallel to the b axis. Mol­ecules are further linked by π–π stacking inter­actions, with centroid–centroid distances of 3.925 (3)–3.926 (3) A, forming a three-dimensional network.
