V. S. Grinev and A. Y. Egorova

Synopsis: Molecules of the title compound are linked into chains by intermolecular C=O...H-N hydrogen bonds and the chains are weakly interconnected by [pi]-[pi] stacking interactions. A comparison of the geometric parameters of the title molecule and several related benzimidazoles and pyrrolidones is presented.

Formula: C16H14N2O
