英文摘要	It is suggested that the hollow coinage-metal icosahedral cage of the [Ag-44(SR)(30)](4-) tetraanion (1a) may be occupied by two hydrogen atoms, giving rise to a dihydridic cluster [H2Ag44(SR)(30)](4-) tetraanion (2b). As a consequence, two series of clusters, with different electron counts, can be formed by chemical means: the 18-electron series [H (x) Ag-44(SR)(30)]((4-x)-) via stepwise protonation of 1a and the 20-electron series [H (x) Ag-44(SR)(30)]((6-x)-) via stepwise deprotonation of 2b (here x = 0, 1, 2). Both series are closed-shell Jelliumatic clusters and expected to be stable. The corresponding members of these two series (for a given x value) are related by a two-electron reduction. These pairs raise the possibility of the hollow icosahedral metal cages in housing a number of hydrogen atoms, either via stepwise protonations or by absorption of hydrogen molecules.; Chemistry, Inorganic & Nuclear; SCI(E); 2; ARTICLE; boonkteo@gmail.com; 4; 883-891; 25
