Abstract

The title salt, C(3)H(10)N(+)·C(14)H(8)F(3)O(2) (-), constitutes the first organic crystal containing a residue of 4,4,4-trifluoro-1-(naphthalen-2-yl)butane-1,3-dione. The terminal -CF(3) group is disordered over two locations [occupancy ratio = 0.830 (7):0.170 (7)]. Bond delocalization involving the two carbonyl groups and the α-carbon was observed. The crystal packing is mediated by several supra-molecular inter-actions, namely charged-assisted N-H⋯O hydrogen bonds, C-H⋯F and C-F⋯F short contacts and C-H⋯π inter-actions.
