| Abstract: | The largest Ln–Fe metal cluster [Gd12Fe14(μ3‐OH)12(μ4‐OH)6(μ4‐O)12(TEOA)6(CH3COO)16(H2O)8]⋅(CH3COO)2(CH3CN)2⋅(H2O)20 ( 1 ) and the core–shell monodisperse metal cluster of 1 a @SiO2 ( 1 a =[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 1 a @SiO2 reveal that encapsulation of one cluster into one silica nanosphere not only effectively decreases intermolecular magnetic interactions but also significantly increases the zero‐field splitting effect of the outer layer Fe3+ ions. |
