Nine isomers of Ge6, Ge62-, Ge 64-, and Ge66- have been searched for by the MP2/6-31+G(d), B3LYP/6-311+G(d), and B3LYP/LANL2DZ electronic structure calculations. Totally 16 isomers are found: six Ge6, three Ge62-, five Ge64-, and two Ge 66-. We discovered that the predicted stable shapes of Ge62-, Ge64-, and Ge 66- are octahedral, pentagonal pyramidal, and hexagonal, respectively, which agrees well with the Wade rule. It is concluded that the electron counting rule governs the structural preference in Ge anion clusters as well as in Si anion clusters.
