A self-assembled pentanuclear single-stranded helicate based on the square-planar coordination geometries

Abstract The copper(II) complex of a new bis-N 4 O-hexdentate Schiff-base, in which two N , N ′-dimethyl- N -(3-(2′-aminoethylimine)-5-(chlorosalicylamine))- N ′-(3-imine-5-chlorosalicylamine) units are connected by an ethylene, was synthesized and structurally characterized in the solid state as a form of pentanuclear single helicate based on the square-planar coordination geometries.
