By the anionic template strategy, we have, for the first time, succeeded in introducing SiO₄^4– into 3d–4f huge clusters, obtaining two novel nanosized clusters with interesting nanosized cores of [Ln₇₈Ni₆₄₍₆₂₎Si₆] (1, Ln = Gd; 2, Ln = Eu). To the best of our knowledge, they are the largest heterometallic clusters incorporated with Si–O tetrahedra. In addition, compound 1 shows a maximum magnetic entropy (−ΔS_m) of 40.63 J kg^–1 K^–1 at 3.0 K at 7 T.

将硅氧四面体掺入新型高核纳米3d-4f杂金属簇中

通过阴离子模板策略，我们首次成功地将SiO ₄^4–引入到3d–4f巨大簇中，获得了两个具有有趣的纳米尺寸[Ln ₇₈ Ni _64（62） Si ₆ ]的新型纳米尺寸簇（1，Ln ＝ Gd；2，Ln ＝ Eu）。据我们所知，它们是与Si-O四面体结合的最大的杂金属簇。此外，化合物1示出了最大磁熵（-Δ小号_米的40.63Ĵ千克）^-1 ķ ^-1在3.0处的K 7 T.
