文章摘要:

Largest Ln-Fe metal cluster of [Gd12Fe14(μ3-OH)12(μ4-OH)6(μ4-O)12(TEOA)6(CH3COO)16(H2O)8]*(CH3COO)2(CH3CN)2* (H2O)20 (1) and core-shell monodisperse metal cluster of 1a@SiO2 (1a = [Gd12Fe14(μ3-OH)12(μ4-OH)6(μ4-O)12(TEOA)6(CH3COO)16 (H2O)8]2+) were prepared. Experimental and theoretical studies on the magnetic properties of 1 and 1a@SiO2 reveal that encapsulation of one cluster into one silica nanosphere not only effectively decreases intermolecular magnetic interaction but also significantly increases the zero-field splitting effect of the outer layer Fe3+ ions.
