1,2-Dimethyl-4,5-diphenyl-benzene determined on a Bruker SMART X2S benchtop crystallographic system.

ABSTRACT

The title compound, C(20)H(18), has two crystallographically independent mol-ecules in the asymmetric unit. The phenyl substituents of mol-ecule A are twisted away from the plane defined by the central benzene ring by 131.8 (2) and -52.7 (3)°. The phenyl substituents of mol-ecule B are twisted by -133.3 (2) and 50.9 (3)°. Each mol-ecule is stabilized by a pair of intra-molecular C(aryl, sp(2))-H⋯π inter-actions, as well as by several inter-molecular C(methyl, sp(3))-H⋯π inter-actions.
