1,2-Bis(3,5-dimethylphenyl)ethane

Abstract

The title compound, C18H22, is a coupling product of two metallated mesitylene molecules. The dihedral angle between the aromatic rings is 11.10 (5)° and the Car—Cm—Cm—Car (ar = aromatic and m = methylene) torsion angle is 179.60 (14)°. No directional interactions beyond normal van der Waals contacts could be identified in the crystal. To our best knowledge, it is the first known coupling product of metallated mesitylene.
