The endohedral cluster anion Pd(3)Sn(8)Bi(6) crystallizes as its K([2.2.2]crypt)(+) salt 1 upon reaction of K([2.2.2]crypt)[Sn(2)Bi(2)]·en and Pd(dppe)(2) in 1,2-diaminoethane (en)/toluene and incorporates a complete Pd(3) triangular cluster within a medium-size 14-vertex cage of Sn and Bi atoms. 1 was characterized by a combination of single crystal diffraction, ESI mass spectrometry, elemental analysis, and magnetic measurements. According to quantum chemical investigations, the Pd(3) triangle interacts only weakly with the Sn/Bi cluster shell despite the relatively small cavity inside the cage.
笼型内包簇阴离子Pd(3)Sn(8)Bi(6)在反应[K([2.2.2]crypt)(2)[Sn(2)Bi(2)]·en 和 Pd(dppe)(2)于 1,2-二氨基乙烷(en)/甲苯中生成其 K([2.2.2]crypt)(+)盐 1，并在中等大小的 Sn 和 Bi 原子 14 顶点笼内包含完整的 Pd(3)三角形簇。1 通过单晶衍射、ESI 质谱、元素分析和磁性测量的组合进行了表征。根据量子化学研究，尽管笼内的空腔相对较小，但 Pd(3)三角形与 Sn/Bi 簇壳仅弱相互作用。
