AI Article Synopsis
- The study visualizes the electron-density distribution in the 1,2-digermacyclobutadiene ring, highlighting its unique electron behavior.
- The GeC ring exhibits a strong Möbius 4π-electron aromatic character, which is distinct from the antiaromatic nature of the all-carbon cyclobutadiene.
- This research suggests that the presence of germanium alters the electronic properties significantly compared to the carbon-only structure.
Article Abstract
We present the visualization of the experimental valence electron-density distribution (EDD) in the isolated 1,2-digermacyclobutadiene ring system, revealing the unique 4π electron-delocalization on the four-membered GeC ring. A remarkably high Möbius 4π-electron aromatic character in the GeC ring can be suggested from theoretical calculations, in sharp contrast to the significant antiaromaticity of the all-carbon cyclobutadiene ring.
