2-Chloro-1-[4-(2,4-difluoro­benz­yl)piperazin-1-yl]ethanone

In the title mol­ecule, C₁₃H₁₅ClF₂N₂O, the piperazine ring is in a chair conformation with the 2,4-difluoro­benzyl and chloro­acetyl substituents in equatorial positions.

1H-1,2,4-Triazol-4-ium (3,4-dichloro­phen­yl)methane­sulfonate

In the title molecular salt, C₂H₄N₃⁺·C₇H₅Cl₂O₃S⁻, C—C—S angle [112.25 (18)°] deviates slightly from that expected for ideal sp³-hybridization geometry. In the crystal, the components are linked by N—H...O and bifurcated N—H...(O,O) hydrogen bonds into chains parallel to [110].
