文摘

The effective magneto鈥搊ptical properties of novel nonanuclear Tb(III) complexes with Tb鈥揙 lattice (specifically, [Tb₉(sal-R)₁₆(渭-OH)₁₀]⁺NO₃^{鈥?/sup>, where sal-R = alkyl salicylate (R = 鈭扖H₃ (Me), 鈭扖₂H₅ (Et), 鈭扖₃H₇ (Pr), or 鈭扖₄H₉ (Bu)) are reported. The geometrical structures of these nonanuclear Tb(III) complexes were characterized using X-ray single-crystal analysis and shape-measure calculation. Optical Faraday rotation was observed in nonanuclear Tb(III) complexes in the visible region. The Verdet constant per Tb(III) ion of the Tb₉(sal-Me) complex is 150 times larger than that of general Tb(III) oxide glass. To understand their large Faraday rotation, electron paramagnetic resonance measurements of Gd(III) complexes were carried out. In this Report, the magneto鈥搊ptical relation to the coordination geometry of Tb ions is discussed.}
