On July 20, 2009, Ako, Ayuk M.; Mereacre, Valeriu; Clerac, Rodolphe; Hewitt, Ian J.; Lan, Yanhua; Buth, Gernot; Anson, Christopher E.; Powell, Annie K. published an article.Product Details of 2160-93-2 The title of the article was Tridecanuclear [MnIII5LnIII8] Complexes Derived from N-tButyl-diethanolamine: Synthesis, Structures, and Magnetic Properties. And the article contained the following:
The synthesis, structures and magnetic properties of a family of heterometallic [MnIII5LnIII8(μ3-OH)12(L2)4(piv)12(NO3)4(OAc)4]- (Ln = Pr, 2; Nd, 3; Sm, 4; Gd, 5; Tb, 6) aggregates are reported. The complexes were obtained from the direct reaction of N-tbutyldiethanolamine (H2L2) with Mn(OAc)2·4H2O and Ln(NO3)3·6H2O in the presence of pivalic acid (pivH) in MeCN under ambient conditions. Compounds 2-6 are isomorphous and crystallize in the monoclinic space group P21/n with four mols. in the unit cell. The complexes have a centrosym. tridecanuclear anionic core consisting of two distorted inner heterometallic [MnIIILnIII3(μ3-OH)4]8+ cubane subunits sharing a common Mn vertex flanked by four edge-sharing heterometallic [MnIIILnIII2(μ3-OH)4]5+ defect cubane units. Complexes 2-6 are the first high-nuclearity 3d-4f aggregates reported to date using tBu-deaH2 as ligand. These compounds show no evidence of slow relaxation behavior >1.8 K, which appears to be the consequence of the very weak or nonexistent magnetic interactions between the MnIII and LnIII ions resulting from the particular angles at the bridging oxygens. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Product Details of 2160-93-2
