Crystal structure, Hirshfeld surface analysis, and calculations of inter-molecular inter-action energies and energy frameworks of 1-[(1-hexyl-1-1,2,3-triazol-4-yl)meth-yl]-3-(1-methyl-ethen-yl)-benzimidazol-2-one.

The benzimidazole moiety in the title mol-ecule, CHNO, is almost planar and oriented nearly perpendicular to the triazole ring. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into a network structure. There are no π-π inter-actions present but two weak C-H⋯π(ring) inter-actions are observed.
