3,3''-Dimethyl-1,1':4',1''-terphenyl

The title compound, C₂₀H₁₈, is centrosymmetric and adopts a twisted conformation. This result contrasts related, unsubstituted systems, where rotational disorder is inevitably found. The different behaviour is rationalized in terms of the absence of π–π interactions in the lattice of the title compound.
