Verdazyl Radical, a Building Block for a Six-Spin-Center 2p-3d-4f Single-Molecule Magnet

Abstract

The versatile verdazyl family provides a new member as its reduced form 1,5-dimethyl-3-[3′-(hydroxymethyl)-2′-pyridine]-6-oxotetrazane (H3vdpyCH2OH). Upon oxidation and deprotonation in the presence of the acetate salts of CoII and DyIII, the vdpyCH2OH radical is able to self-assemble [(vdpyCH2O)2Co2Dy2ac8] (Hac = HO2CCH3), a 2p-3d-4f cluster displaying single-molecule-magnet properties.
