Atomic Structure and Electronic Properties of Anionic Germanium–Zirconium Clusters

Resumo

This paper presents spatial structure optimization results and calculated electronic spectra for ZrGe_n⁻ (n = 8–20) anion clusters. Comparison of density-functional calculation results and available experimental data allows us to identify real spatial structures of the clusters. The formation of stable endohedral ZrGe_n⁻ clusters is possible for n ≥ 12. The clusters with a smaller number of germanium atoms predominantly have exohedral structures.
