Aerobic oxidation of a disulfide to its sulfonate leading to supramolecular pyridine-2-sulfonato Cu(II) and Zn(II) complexes

Abstract

A one-dimensional copper(II) complex with pyridine-2-sulfonate donors, [{Cu(3-mpSO₃)₂}_n] (3-mpSO₃ = 3-methylpyridine-2-sulfonate), is formed via the air oxidation of 3-mpds (2,2′-bis(3-methylpyridyl)disulfide) in the presence of CuBr₂, and a mononuclear zinc complex, [Zn(3-mpSO₃)₂(H₂O)₂], which has two-dimensional H-bonded networks and luminescent properties in solid state, is prepared by the reaction of ZnBr₂ with 3-mpSO₃H.
