Abstract

A Mn^III-salen-type complex with a diamagnetic [Co ^III(CN)₆]^3- moiety, [Mn^III(5-TMAM(R) -salmen)(H₂O)Co^III(CN)₆]·7H ₂O·MeCN [1; 5-TMAM(R)-salmen = (R)-N,N′-(1- methylethylene)bis(5-trimethylammoniomethylsalicylideneiminate], was prepared. From direct-current magnetic susceptibilities, magnetization, and high-field and multifrequency electronic spin resonance measurements on powdered samples, 1 has a significant uniaxial anisotropy. Frequency-dependent alternating-current susceptibility signals were clearly observed, indicating slow magnetic relaxation. Thus, complex 1 behaves as a single-ion magnet.
