Abstract

The title compound, C17H7F8N3O, was obtained via the reaction of 1-azido-2,3,4,5,6-penta-fluoro-benzene with 4,4,4-tri-fluoro-1-(p-tol-yl)butane-1,3-dione using tri-ethyl-amine as a base catalyst and solvent. The dihedral angles between the penta-fluoro-phenyl (A), triazole (B) and p-tolyl (C) rings are A/B = 62.3 (2), B/C = 43.9 (3) and A/C = 19.1 (3)°. In the crystal, the mol-ecules are linked by C-H⋯F and C-H⋯O hydrogen bonds as well as by aromatic π-π stacking inter-actions into a three-dimensional network. To further analyse the inter-molecular inter-actions, a Hirshfeld surface analysis was performed.
