Crystal structure, Hirshfeld surface analysis, and calculations of inter­molecular inter­action energies and energy frameworks of 1-[(1-hexyl-1H-1,2,3-triazol-4-yl)meth­yl]-3-(1-methyl­ethen­yl)-benzimidazol-2-one

In the title mol­ecule, the benzimidazole moiety is oriented almost perpendicular to the triazole ring. In the crystal, C—H⋯O hydrogen bonds link the mol­ecules into a network structure.

The benzimidazole moiety in the title mol­ecule, C₁₉H₂₅N₅O, is almost planar and oriented nearly perpendicular to the triazole ring. In the crystal, C—H⋯O hydrogen bonds link the mol­ecules into a network structure. There are no π–π inter­actions present but two weak C—H⋯π(ring) inter­actions are observed. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (62.0%), H⋯C/C⋯H (16.1%), H⋯N/N⋯H (13.7%) and H⋯O/O⋯H (7.5%) inter­actions. Evaluation of the electrostatic, dispersion and total energy frameworks indicate that the stabilization is dominated via the dispersion energy contributions in the title compound.
