title: A diaryl-terminated hexa-1,5-diyne-3,4-dione.
abstract: The structure of bis(4-tert-butyl-2,6-dimethylphenyl)hexa-1,5-diyne-3,4-dione, C30H34O2, has been determined, revealing an extended s-trans conformation of the dione and the two ynone moieties, which are shielded by the flanking methyl substituents. The structural parameters and the packing arrangement suggest little electronic delocalization between the two ynone moieties.
