Sublimable without decomposition is the first barium triple‐decker sandwich complex [( 4 Cp)Ba(cot)Ba( 4 Cp)] ( 4 Cp=C 5 H i Pr 4 ; cot=cyclooctatetraene; see picture). Short distances (significantly below the sum of Van der Waals radii) between two of the methyl groups of each 4 Cp ligand indicate a Ba⋅⋅⋅CH 3 interaction.
