Synthesis, structure and properties of a new NH-1,2,3-triazole-based octanuclear copper(II) complex

An octanuclear copper(II) complex constructed by NH-1,2,3-triazole has been synthesized. The complex exhibit overall antiferromagnetic coupling via hydroxyl groups, κ2-N,N-trizaoles and κ3-N,N,N-trizaoles and displays fluorescent quenching due to intra-ligand and ligand-to-metal charge transfer.93
