4,4'-Dibromo-2,2'-[m-phenyl-enebis(nitrilo-methanylyl-idene)]diphenol.

ABSTRACT: The title compound, C(20)H(14)Br(2)N(2)O(2), is a dibasic tetra-dentate Schiff base and reveals intra-molecular O-H?N hydrogen bonds between the hy-droxy 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 mol-ecules are stacked in columns along the c axis through ?-? inter-actions, the shortest centroid-centroid distance being 3.872?(3)?Å.
