Dineopentylprehnitene (1,2,3,4-tetramethyl-5,6-dineopentylbenzene) at 296 and 223 K.
The title substance, C20H34, crystallized in the centrosymmetric space group C2/c with a single molecule as the asymmetric unit. The molecule is quite crowded intramolecularly, and has a notably non-planar benzene ring. There is, however, virtually no intermolecular crowding.
