Abstract

A MnIII-salen-type complex with a diamagnetic [Co III(CN)6]3- moiety, [MnIII(5-TMAM(R) -salmen)(H2O)CoIII(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.
