Fig. 2: The selected valence molecular orbitals and chemical components of the electron density of Ge244−.
From: Symmetry collapse due to the presence of multiple local aromaticity in Ge244−

a Selected lowest-lying and frontier valence molecular orbitals in the Ge244− cluster. Different phases of molecular orbitals are represented with different colors. Positive: magenta; negative: purple. b The chemical components of the valence-electron density of Ge244− with the corresponding electron populations from the EDDB method. Isosurface value is set at ±0.015 |e|.
