(E)-1,2-Bis(4-methyl-phen-yl)ethane-1,2-dione.

ABSTRACT: In the mol-ecule of the title compound, C(16)H(14)O(2), a substituted benzil, the dicarbonyl unit has an s-trans conformation. This conformation is substanti-ated by the O-C-C-O torsion angle of 108.16?(15)°. The dihedral angle between the two aromatic rings is 72.00?(6)°. In the crystal structure, neighbouring mol-ecules are linked together by weak inter-molecular C-H?O hydrogen bonds and weak inter-molecular C-H?? inter-actions. In addition, the crystal structure is further stabilized by inter-molecular ?-? inter-actions with centroid-centroid distances in the range 3.6000?(8)-3.8341?(8)?Å.
