Synthesis, crystal structure and Hirshfeld surface analysis of [1-(4-bromophenyl)-1H-1,2,3-triazol-4-yl]methyl 2-(4-nitrophenoxy)acetate

The title compound, C 17 H 13 BrN 4 O 5 , was synthesized by a Cu 2 Br 2 -catalysed Meldal–Sharpless reaction between 4-nitrophenoxyacetic acid propargyl ether and para -bromophenylazide, and characterized by X-ray structure determination and 1 H NMR spectroscopy. The molecules, with a near-perpendicular orientation of the bromophenyl-triazole and nitrophenoxyacetate fragments, are connected into a three-dimensional network by intermolecular C—H...O and C—H...N hydrogen bonds (confirmed by Hirshfeld surface analysis), π–π and Br–π interactions.
