Bottom Line: A new tetra-dentate unsymmetrical Schiff base, C(20)H(15)BrN(2)O(2), has been synthesized from 4-bromo-o-phenyl-enediamine and salicylaldehyde in refluxing ethanol.The dihedral angles between the two hydroxy-phenyl rings and the bromo-o-phenyl-enediiminatoin group are 68.6 (1) and 8.7 (1)°; the dihedral angle between the two hydroxy-phenyl rings is 70.3 (1)°.There are two relatively strong intra-molecular of O-H⋯N hydrogen bonds.
