Abstract

The electronic properties of germanium and tin clusters containing a transition- or lanthanide-metal atom from group 3, 4, or 5, MGe n (M = Sc, Ti, V, Y, Zr, Nb, Lu, Hf, and Ta) and MSn n (M = Sc, Ti, Y. Zr, and Hf), were investigated by anion photoelectron spectroscopy at 213 nm. In the case of the group 3 elements Sc, Y, and Lu, the threshold energy of electron detachment of MGe n - exhibits local maxima at n = 10 and 16, while in the case of the group 4 elements Ti, Zr, and Hf, it exhibits a local minimum only at n = 16, associated with the presence of a small bump in the spectrum. A similar behavior is observed for MSn n - around n = 16, and these electronic characteristics of MGe n and MSn n are closely related to those of MSi n. Compared to MSi n, however, the larger cavity size of a Ge n cage allows metal atom encapsulation at a smaller size n. A cooperative effect between the electronic and geometric structures of clusters with a large cavity of Ge 16 or Sn 16 is discussed together with the results of experiments that probe their geometric stability via their reactivity to H 2O adsorption.
