A dinuclear copper(II) complex bridged simultaneously by end-on azido, bromo and diazole (N2) groups exhibiting strong ferromagnetic exchange. X-Ray structure and magnetic properties

Abstract

The tetradentate ligand 2,5-di-(2′-methylpyridylthio)thiadiazole (DPTD) forms a dinuclear, triply bridged, copper(II) complex, involving end-on µ₂-1,1-azido, µ₂-bromo and µ₂-1,2-thiadiazole (N₂) bridges, which exhibits a strong ferromagnetic interaction between adjacent copper centres, a feature present only in a very limited number of dicopper(II) complexes.
