Novel Hexanuclear Copper(II) Complex Built from a Simple Tetrachelating Triazole Ligand: Synthesis, Structure, and Magnetism

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 CuII centers and two clearly distinguishable antiferromagnetic J1 (−234 cm–1) and J2 (−35 cm–1) coupling constants.
