A trinuclear copper (II) complex derived from a chiral [3 + 3] phenol-based macrocycle: Synthesis, structure and magnetic properties

• A trinuclear Cu(II) complex has been synthesized.
• CD spectra of the bulk samples have been measured.
• Variable temperature magnetic data have also been characterized.

An enantiopure trinuclear Cu(II) complex of chiral phenol-based macrocyclic polyamine ligand, which is derived from the [3 + 3] condensation of 3,5-diformyl-4-hydroxyzoic acid ethyl ester with (1R,2R)-1,2-diaminocyclohexane and followed by borohydride reduction, has been synthesized and characterized. The circular dichroism (CD) spectra confirmed its structural chirality in the bulk sample. Variable temperature magnetic data indicated that there is an antiferromagnetic coupling between the metal centers in the complex.
