A new easy symmetric 3,5-disubstituted 1,2,4-triazole ligand (H₃diV) by reaction with an excess of copper(II) salt has afforded a novel hexanuclear compound (Cu/HdiV ratio of 6:2) through a bis(trans–cis–cis–trans) binding mode, exhibiting two types of Cu^II centers and two clearly distinguishable antiferromagnetic J₁ (−234 cm^–1) and J₂ (−35 cm^–1) coupling constants.
