合成了[K([2.2.2]cret)](+)二元铅铋锌阴离子盐，并与ZnPh_2或Ni(CoD)(2)反应生成了三元金属间化合物Ni-铅-铋或锌铅铋簇合物，证明了使用具有全等电子原子的二元前驱体是合成这类簇合物的有效途径。PB-207核磁共振和电喷雾质谱提供了对二元或三元笼子的溶液行为的洞察。
Syntheses of [K([2.2.2]crypt)](+) salts of binary Pb-Bi Zintl anions and their reaction with ZnPh2 or Ni(cod)(2), yielding ternary intermetalloid Ni-Pb-Bi or Zn-Pb-Bi clusters, proved the use of binary precursors with fully isoelectronic atoms as an efficient and thus valuable synthetic approach to this class of clusters. Pb-207 NMR and ESI mass spectra provided insight into the solution behavior of the binary or ternary cages.
