Abstract

In the title ion-pair, C(22)H(29)Cl(2)N(4)O(2) (+)·C(2)F(3)O(2) (-), ammonium-carboxyl-ate N-H⋯O 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 chloro-phenyl ring. The other imino N atom acts as a hydrogen-bond acceptor from a phenolate O atom.
