Nickel(II) magnets: A new family of trinuclear NiII complexes with phenoxido (μ2 and μ3), hydroxido (μ3), and μ2-Cl, μ1,1-NCO, or μ1,1-N3 bridges have been prepared that form face-sharing coordination polyhedra (see figure). The three complexes exhibit a dominant ferromagnetic exchange coupling with sizable uniaxial anisotropy. The slow magnetization relaxation, the hysteresis of the pulsed-field magnetization, a magnetic easy axis, and the high-frequency EPR spectra show that these complexes constitute a new class of single-molecule magnets.
