A novel antiferromagnetically coupled, dimeric, dodecanuclear copper(II) complex involving two macrocyclic ligands each with a ‘benzene-like’ arrangement of six copper centres

Abstract

Template condensation of 2,6-diformyl-4-methylphenol with 1,3-diamino-2-hydroxypropane, in the presence of copper(II) nitrate and a base, results in the formation of a novel dimeric, dodecacopper(II) complex of a 30-membered macrocyclic ligand (H₆M), with a pseudo-hexagonal, ‘benzene-like’ arrangement of metal centres and an alternating double (µ₂-OPh, µ₂-OH) and single (µ₂-OR) bridge arrangement within each ring.
