Abstract

In this study, four new piperazinium salts, namely, 4-phenyl­piperazin-1-ium 4-eth­oxy­benzoate monohydrate, C9H9O3·C10H15N2·H2O (I); 4-phenyl­piperazin-1-ium 4-meth­oxy­benzoate monohydrate, C10H15N2·C8H7O3·H2O (II); 4-phenyl­piperazin-1-ium 4-methyl­benzoate monohydrate, C10H15N2·C8H7O2·H2O (III); and 4-phenyl­piperazin-1-ium tri­fluoro­acetate 0.12 hydrate, C10H15N2·C2F3O2·0.12H2O (IV), have been synthesized. The single-crystal structures of these compounds reveal that all of them crystallize in the triclinic P[\overline{1}] space group and the crystal packing of (I)–(III) is built up of ribbons formed by a combination of hydrogen bonds of type N—H⋯O, O—H⋯O and other weak inter­actions of type C—H⋯O and C—H⋯π, leading to a three-dimensional network. In the crystal of (IV), the cations and the anions are connected by C—H⋯O, N—H⋯O and C—H⋯F hydrogen bonds and by C—H⋯π inter­actions, forming sheets which in turn inter­act to maintain the crystal structure by linking through the oxygen atoms of water mol­ecules and van der Waals inter­actions, giving the whole structure.
