摘要：

The title salt, C3H10N+center dot C14H8F3O2-, constitutes the first organic crystal containing a residue of 4,4,4-trifluoro-1-(naphthalen-2-yl)butane-1,3-dione. The terminal -CF3 group is disordered over two locations [occupancy ratio = 0.830 (7):0.170 (7)]. Bond delocalization involving the two carbonyl groups and the alpha-carbon was observed. The crystal packing is mediated by several supramolecular interactions, namely charged-assisted N-H center dot center dot center dot O hydrogen bonds, C-H center dot center dot center dot F and C-F center dot center dot center dot F short contacts and C-H center dot center dot center dot pi interactions.
