Abstract:
The title salt, C(9)H(18)NO(+)·C(7)H(3)ClNO(4) (-), was obtained as an unexpected product of the reaction of 4-chloro-3-nitro-benzoyl isothio-cyanate with pyrrolidine. The six-membered ring of the 4-oxopiperidinium cation adopts a chair conformation. In the crystal structure, two cations and three anions are linked together by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds and arranged diagonally along the ac face.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
