Abstract

Condensation of pentaethylenehexamine and 3-bromo-5-chlorosalicylaldehyde yielded the bisimidazolidine Schiff base ligand 5,6\'-(1E,1\'E)-(2,2\'-(3,3\'-(ethane-1,2- diyl)bis(2-(3-bromo-5-chloro-2-hydroxyphenyl)imidazolidine-3,1-diyl))bis(ethane- 2,1-diyl))bis(azan-1-yl-1-ylidene)bis(methan-1-yl-1-ylidene)bis(2-bromo-4- chlorophenol), H₄L. This diimine could be suitably characterised both in the solid state and in solution.
