New mononuclear, cyclic tetranuclear, and 1-D helical-chain Cu(II) complexes formed by metal-assisted hydrolysis of 3,6-di-2-pyridyl-1,2,4,5-tetrazine (DPTZ): crystal structures and magnetic properties

Research has been conducted on the 1-D helical-chain Cu(II) complexes. The synthesis, characterization, magnetic properties and crystal structure of these complexes have been carried out and the effect of the counteranions on the complexes' formation and the hydrolysis process mechanism are discussed.
