Crystal structure, Hirshfeld surface analysis, calculations of inter-molecular inter-action energies and energy frameworks and the DFT-optimized mol-ecular structure of 1-[(1-butyl-1-1,2,3-triazol-4-yl)meth-yl]-3-(prop-1-en-2-yl)-1-benzimidazol-2-one.

The benzimidazole entity of the title mol-ecule, CHNO, is almost planar (r.m.s.

Synthesis, structure and Hirshfeld surface analysis of 1,3-bis-[(1-octyl-1-1,2,3-triazol-4-yl)meth-yl]-1-benzo[]imidazol-2(3)-one.

The title mol-ecule, CHNO, adopts a conformation resembling a two-bladed fan with the octyl chains largely in fully extended conformations. In the crystal, C-H⋯O hydrogen bonds form chains of mol-ecules extending along the -axis direction, which are linked by weak C-H⋯N hydrogen bonds and C-H⋯π inter-actions to generate a three-dimensional network. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (68.
