A new easy symmetric 3,5-disubstituted
1,2,4-triazole ligand (H<sub>3</sub>diV) 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<sup>II</sup> centers and
two clearly distinguishable antiferromagnetic <i>J</i><sub>1</sub> (−234 cm<sup>–1</sup>) and <i>J</i><sub>2</sub> (−35 cm<sup>–1</sup>) coupling constants.
