Abstract: In the title ion-pair, C22H29Cl2N4O2+·C2F3O2-, ammonium-carboxylate N-HO hydrogen bonds link two cations and two anions about a centre of inversion to generate a hydrogen-bonded tetramer. In the cation, one of the imino N atoms is protonated and donates a hydrogen bond to the O atom of the adjacent chlorophenyl ring. The other imino N atom acts as a hydrogen-bond acceptor from a phenolate O atom.
