3a-Phenyl-2,3,3a,4-tetra­hydro-1H-benzo[d]pyrrolo­[1,2-a]imidazol-1-one, a potential plant-growth regulator

Mol­ecules of the title compound are linked into chains by inter­molecular C=O...H—N hydrogen bonds and the chains are weakly inter­connected by π–π stacking inter­actions. A comparison of the geometric parameters of the title mol­ecule and several related benzimid­azoles and pyrrolidones is presented.
