Quinoxaline radical-bridged transition metal complexes with very strong antiferromagnetic coupling

Abstract

A new family of radical-bridged compounds, (Cp*2Co)[M2Cl4(dpq)] (M = Fe (1), Co (2), Zn(3)), (dpq = 2,3-di(2-pyridyl)-quinoxaline) is reported. Magnetic studies, DFT and ab initio calculations reveal strong antiferromagnetic metal-radical interactions with coupling constants of J = -213.1 and -218.8 cm-1 for 1 and 2, respectively.
