On May 28, 2010, Mereacre, Valeriu; Akhtar, Muhammad Nadeem; Lan, Yanhua; Ako, Ayuk M.; Clerac, Rodolphe; Anson, Christopher E.; Powell, Annie K. published an article.Application In Synthesis of 2,2′-(tert-Butylazanediyl)diethanol The title of the article was Structures and magnetic properties of MnIII4LnIII4 aggregates with a “square-in-square” topology. And the article contained the following:
The structures and magnetic properties of a family of new octanuclear heterometallic 3d-4f complexes [MnIII4LnIII4(μ3-OH)4(μ2,η1-X)4(O2CBut)8(t-bdea)4]·solv, where X = N3-, Ln = Y (1), Eu (2), Gd (3), Tb (4), Dy (5), Ho (6); X = OCN-, Ln = Dy (7); X = NO3-, Ln = Gd (8), Tb (9), Dy (10), Ho (11), Er (12); solv = MeCN or toluene, are reported. The metal topol. in the aggregates can be described as consisting of a Ln4-square inscribed in a Mn4-square. Complexes 1-7 are prepared by the reactions of t-butyldiethanolamine (t-bdeaH2) with a preformed hexanuclear manganese pivalate complex [Mn6], the resp. lanthanide salt and either NaN3 or NaNCO, while 8-12 are obtained from the direct reaction of Mn(OAc)2, Ln(NO3)3·xH2O and t-butyldiethanolamine. The magnetic properties of all the complexes were investigated using variable temperature magnetic susceptibility and magnetization measurements. Similar magnetic behavior was observed for compounds containing the same lanthanide, indicating that changing the bridging ligand X does not have a significant effect on the magnetic behavior. The TbIII and DyIII compounds 4, 5, 7, 9 and 10 all show frequency-dependent ac susceptibilities indicative of a slow relaxation of magnetization and are therefore considered as Single-Mol. Magnets. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Application In Synthesis of 2,2′-(tert-Butylazanediyl)diethanol
