Chen, Sihuai; Mereacre, Valeriu; Zhao, Zhiying; Zhang, Wanwan; Zhang, Mengsi; He, Zhangzhen published an article in 2018, the title of the article was Targeted replacement: systematic studies of dodecanuclear {MIII6LnIII6} coordination clusters (M = Cr, Co; Ln = Dy, Y).Name: 2,2′-(tert-Butylazanediyl)diethanol And the article contains the following content:
Three dodecanuclear 3d-4f coordination clusters, [CrIII6LnIII6(μ3-OH)8(tbdea)6(C6H5COO)16]·2H2O (Ln = Dy (1), Y (2)) and [CoIII6DyIII6(μ3-OH)8(nbdea)6(m-CH3C6H4COO)16]·2H2O·2CH3CN (3), have been synthesized under solvothermal conditions and characterized. Single-crystal x-ray diffraction anal. revealed that all three compounds possess an analogous {M6IIILnIII6} core (M = Cr, Co; Ln = Dy, Y) and dc magnetic susceptibility studies indicated that the magnetic exchange couplings between DyIII ions are dominant antiferromagnetic, while the CrIII-DyIII interactions are weakly ferromagnetic. Furthermore, the ac magnetic susceptibility measurements showed that both CrIII6DyIII6 compound 1 and CoIIi6DyIII6 compound 3 containing highly anisotropic DyIII ions displayed single-mol. magnetic (SMM) behavior with the energy barrier Ueff increasing from 12.8 K (for 1) to 20.8 K (for 3), indicating that weak 3d-4f exchange couplings enhance the QTM and reduce the energy barrier. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Name: 2,2′-(tert-Butylazanediyl)diethanol
