Propylammonium 4,4,4-trifluoro-1-(naphthalen-2-yl)butane-1,3-dionate

Abstract

The title salt, C3H10N+·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 α-carbon was observed. The crystal packing is mediated by several supramolecular interactions, namely charged-assisted N—H...O hydrogen bonds, C—H...F and C—F...F short contacts and C—H...π interactions.
