| Popis: | The title compound, C19H17ClN4O2, was obtained via a two-step synthesis involving the enol-mediated click Dimroth reaction of 4-azidoanisole with methyl 3-cyclopropyl-3-oxopropanoate leading to the 5-cyclopropyl-1-(4-methoxyphenyl)-1H-1,2,3-triazole-4-carboxylic acid and subsequent acid amidation with 4-chloroaniline by 1,1′-carbonyldiimidazole (CDI). It crystallizes in space group P21/n, with one molecule in the asymmetric unit. In the extended structure, two molecules arranged in a near coplanar fashion relative to the triazole ring planes are interconnected by N—H...N and C—H...N hydrogen bonds into a homodimer. The formation of dimers is a consequence of the above interaction and the edge-to-face stacking of aromatic rings, which are turned by 58.0 (3)° relative to each other. The dimers are linked by C—H...O interactions into ribbons. DFT calculations demonstrate that the frontier molecular orbitals are well separated in energy and the HOMO is largely localized on the 4-chlorophenyl amide motif while the LUMO is associated with aryltriazole grouping. A Hirshfeld surface analysis was performed to further analyse the intermolecular interactions. |
