The aim is to investigate the unexpected dimerization of an antiaromatic homoHPHAC monocation.
Examined the structural properties in solution and solid state
Utilized acetone-d6 as a solvent at 298 K
Demonstrated formation of a rare slipped π-stacked dimer structure
Identified this dimerization as unique for antiaromatic compounds
Resumen
An antiaromatic homoHPHAC monocation unexpectedly forms a slipped π-stacked structure in solution and the solid state, representing a rare example of an antiaromatic π-dimer. In acetone- d 6 at 298 K, the...
