Abstract

A new one-dimensional chain complex, Mn(hfac)2-bridged [2-(3-pyridyl)(nitronyl nitroxide)Mn(hfac)2]2, was prepared and its structure and magnetic properties were elucidated; the complex exhibited a large antiferromagnetic interaction of J1 = −185 K between the three Mn(II) atoms and the two nitronyl nitroxides to give S = 13/2 spin units and a small ferromagnetic interaction of J3′ = +0.02 K between these spin units at low temperatures (50–1.9 K), compatible with the theoretical analysis for model compounds.
