1-Benzyl-3-methylquinoxalin-2(1H)-one

The asymmetric unit of the title compound, C16H14N2O, contains three independent molecules differing primarily in the orientations of the benzyl groups. Each independent molecule forms inversion related dimers via offset π-stacking interactions. For two of these dimers, stacks are formed approximate...

Description
Summary:The asymmetric unit of the title compound, C16H14N2O, contains three independent molecules differing primarily in the orientations of the benzyl groups. Each independent molecule forms inversion related dimers via offset π-stacking interactions. For two of these dimers, stacks are formed approximately along the a-axis direction by a combinations of C—H...N and C—H...π(ring) contacts, in addition to the offset π-stacking interactions. The third set of dimers are also stacked in the same direction but only by pairwise C—H...N hydrogen bonds.
