A hydride (H)-doped bimetallic superatom (HPdAu) was produced by reacting BH with an oblate (PdAu) superatom protected by PPh. The H atom in (HPdAu) survived during the sequential addition of Au(I)Cl to form an (HPdAu) superatom, in sharp contrast to the proton release from a H-doped pure gold superatom (HAu) in the growth process to (Au). Single-crystal X-ray diffraction analysis and density functional theory calculations on (HPdAu) showed that the interstitially doped H atom induced a notable deformation of the core.
通过使硼氢化钠（BH）与由三苯基膦（PPh）保护的扁球形（钯金，PdAu）超原子反应，制备了一种氢化物（H）掺杂的双金属超原子（HPdAu）。在依次添加氯化亚金（Au(I)Cl）形成（HPdAu）超原子的过程中，（HPdAu）中的氢原子得以保留，这与在从氢掺杂的纯金超原子（HAu）生长为（Au）的过程中质子释放形成了鲜明对比。对（HPdAu）进行的单晶X射线衍射分析和密度泛函理论计算表明，间隙掺杂的氢原子引起了核心的显著变形。
