In the title compound, C(14)H(12)N(2)O(2), the asymmetric unit comprises one half-mol-ecule with an inversion center between the pyridine rings. The rings are trans coplanar with the acetyl groups deviating slightly from the mean planes, making a dihedral angle of 4.63 (4)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds, forming a supra-molecular sheet paral...

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 s...
