The title compound, (RS)-3,5-dichloro-2-[[(1-phenylethyl)imino]methyl]phenol, C(15)H(13)Cl(2)NO, was synthesized from racemic 1-phenylethylamine and 3,5-dichlorosalicylaldehyde. The pi-conjugate system around the imine group is essentially planar in the phenol-imine tautomer. Intramolecular O...N hydrogen-bond and intermolecular C-H...pi interactions are present in the crystal structure.

Eleven mononuclear copper(II), nickel(II), zinc(II) and cobalt(II) complexes of Schiff base ligands derived from 3,5-dibromosalicylaldehyde/3,5-dichlorosalicylaldehyde were synthesized and determined by single crystal X-ray analysis. The crystal structures of complexes 1, 2, 4, 5, 6, 8 and 11 present the square-planar
