2,2′-[5-Bromo-o-phenyl­enebis(nitrilo­methyl­idyne)]diphenol

A new tetra­dentate unsymmetrical Schiff base, C(20)H(15)BrN(2)O(2), has been synthesized from 4-bromo-o-phenyl­enediamine and salicylaldehyde in refluxing ethanol. The dihedral angles between the two hydroxy­phenyl rings and the bromo-o-phenyl­enediiminatoin group are 68.6 (1) and 8.7 (1)°; the dih...

Sumario:A new tetra­dentate unsymmetrical Schiff base, C(20)H(15)BrN(2)O(2), has been synthesized from 4-bromo-o-phenyl­enediamine and salicylaldehyde in refluxing ethanol. The dihedral angles between the two hydroxy­phenyl rings and the bromo-o-phenyl­enediiminatoin group are 68.6 (1) and 8.7 (1)°; the dihedral angle between the two hydroxy­phenyl rings is 70.3 (1)°. There are two relatively strong intra­molecular of O—H⋯N hydrogen bonds.
