4,4′-Dibromo-2,2′-[m-phenyl­enebis(nitrilo­methanylyl­idene)]diphenol

The title compound, C(20)H(14)Br(2)N(2)O(2), is a dibasic tetra­dentate Schiff base and reveals intra­molecular O—H⋯N hydrogen bonds between the hy­droxy O atoms and the imino N atoms. The dihedral angle between the central and terminal benzene rings is 39.7 (1)°. In the crystal, the compound is dis...

description The title compound, C(20)H(14)Br(2)N(2)O(2), is a dibasic tetra­dentate Schiff base and reveals intra­molecular O—H⋯N hydrogen bonds between the hy­droxy O atoms and the imino N atoms. The dihedral angle between the central and terminal benzene rings is 39.7 (1)°. In the crystal, the compound is disposed about a crystallographic mirror plane parallel to the ac plane passing through the two central C atoms. The mol­ecules are stacked in columns along the c axis through π–π inter­actions, the shortest centroid–centroid distance being 3.872 (3) Å.
