Kloewer, Frederik; Lan, Yanhua; Nehrkorn, Joscha; Waldmann, Oliver; Anson, Christopher E.; Powell, Annie K. published an article in 2009, the title of the article was Modelling the Magnetic Behaviour of Square-Pyramidal CoII5 Aggregates: Tuning SMM Behaviour through Variations in the Ligand Shell.Application In Synthesis of 2,2′-(tert-Butylazanediyl)diethanol And the article contains the following content:
Three new μ4-bridged CoII5 clusters with similar core motifs were synthesized using N-tert-butyldiethanolamine (tbdeaH2) and pivalic acid (piv): [CoII5(μ4-N3)(tbdea)2(μ-piv)4(piv)(MeCN)2]·MeCN (1), [CoII5(μ4-Cl)(Cl)(tbdea)2(μ-piv)4(pivH)2] (2) and [CoII5(μ4-N3)(Cl)(tbdea)2(μ-piv)4(pivH)2] (3). Magnetic measurements were performed for all three compounds While the chloride-bridged cluster 2 does not show an out-of-phase signal, which excludes single-mol. magnet (SMM) behavior, the azide-bridged compounds 1 and 3 show out-of-phase signals as well as frequency dependence of the a.c. susceptibility, as expected for SMMs. Is a SMM with zero-field quantum tunnelling of the magnetization at 1.8 K. Compound 3 is likely a SMM with a blocking temperature well <1.8 K. The authors established a phys. model to fit the χT vs. T and M vs. B curves of the three compounds to reproduce the observed SMM trend. The anal. showed that small changes in the ligand shell modify not only the magnitude of exchange constants, but also affect the J and g matrixes in a nontrivial way. 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
