Single-molecule magnets: a family of MnIII/CeIV complexes with a [Mn8CeO8]12+ core.
Four heterometallic, enneanuclear Mn8Ce clusters [Mn8CeO8(O2CMe)12(H2O)4] (4), [Mn8CeO8(O2CMe)12(py)4] (5), [Mn8CeO8(O2CPh)12(MeCN)4] [Mn8CeO8(O2CPh)12(dioxane)4] (6), and [Mn8CeO8(O2CCHPh2)12(H2O)4] (7) have been prepared by various methods. Their cores are essentially isostructural and comprise a nonplanar, saddlelike [MnIII8O8]8+ loop containing a central CeIV ion attached to the eight micro...
متن کاملLanthanide triple-stranded helical complexes with a substituted 2,6-pyridinedicarboxylate†
A 4-aminophenylethynyl substituent has been grafted into the 4-position of the pyridine ring in dipicolinic acid to yield ligand L the pKa’s of which are 8.77(5), 3.54(3), 2.58(1) and 1.01(3). Ligand L 4 reacts with trivalent lanthanide ions to give stable triple-stranded helical complexes in water (logβ13 = 13.7(1) for Eu). The separation of the contact and pseudocontact contributions to the N...

Superconductivity with a Twist
Superconductivity and magnetism are typically antithetical forms of order. After all, in conventional superconductors, magnetic impurities are destructive to superconductivity as they break Cooper pairs [1]. But the discovery in 1979 of so-called heavy fermion superconductivity, found near an antiferromagnetic phase, led to a shift in thinking on this subject [2]. Since then, some of the most i...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
