Abstract

We report the experimental and theoretical characterization of antiaromaticity in an all-metal system, Li3Al4, which we produced by laser vaporization and studied with the use of photoelectron spectroscopy and ab initio calculations. The most stable structure of Li3Al4 found theoretically contained a rectangular Al44– tetraanion stabilized by the three Li+ ions in a capped octahedral arrangement. Molecular orbital analyses reveal that the rectangular Al44– tetraanion has four π electrons, consistent with the 4n Hückel rule for antiaromaticity.
