Conformational difference between mono- and diprotonated cis-2,5-diphenylpiperazinium salts in the solid state.
Monohydrochlorides of cis-2,5-diphenylpiperazine assume a chair conformation, while the corresponding dihydrochlorides assume a boat form regardless of the substituent(s) at the nitrogen atom.
