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.
