Synthesis, crystal structure and Hirshfeld surface analysis of [1-(4-bromo-phen-yl)-1H-1,2,3-triazol-4-yl]methyl 2-(4-nitro-phen-oxy)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-nitro-phen-oxy-acetic acid propargyl ether and para-bromo-phenyl-azide, and characterized by X-ray structure determination and (1)H NMR spectroscopy. The mol-ecules, with a near-perpendicular orientation of the bromo-phenyl-triazole and nitro-phen-oxy-acetate fragments, are connected into a three-dimensional network by inter-molecular C-H⋯O and C-H⋯N hydrogen bonds (confirmed by Hirshfeld surface analysis), π-π and Br-π inter-actions.
