Copper(I) complexes of 2-(Phenyliminomethyl)pyridine and some related ligands

Abstract

A number of copper(I) complexes of anils of pyridine-2-carbaldehyde with iodide and bromide as ions have been prepared. The iodo compounds belong to the series [CuLI]₂, thought to have a dimeric iodide-bridged structure in the solid state. The compounds with bromide appear to have the ion-pair structure [CuL₂] [CuBr₂]. The low solubility of both types of complex in organic solvents severely limits their study.
