Utilizing a customized metal cluster source in tandem with a flow tube reactor and a reflectron time-of-flight mass spectrometer, we have obtained well-resolved pure metal clusters Pt n – and observed their gas-phase reactions with a few small gas molecules. Interestingly, the remarkable inertness of Pt 10 – was repeatedly observed in different reactions. Meanwhile, we have determined the structure of Pt 10 – within a regular tetrahedron. Considering that Pt possesses 5d 9 6s 1 electron configuration, the tetrahedral Pt 10 – exhibits unexpected stability at neither a magic number of valence electrons nor a shell closure of geometric structure. Comprehensive theoretical calculations unveil the stability of Pt 10 – is significantly associated with the all-metal aromaticity. In addition to the classical total aromaticity, which is mainly due to 6s electrons, there is unique beta-aromaticity ascribed to spin-polarized beta 5d electrons pertaining to singly occupied multicenter bonds. Further, we demonstrate the superatomic feature of such a transition metal cluster Pt 10 – , as Pt 6 @Pt 4 – , in mimicking methane. |
