Abstract

The title compound, C17H20F2N22+·2C2Cl3O2−·0.4H2O, has twofold protonated N atoms. The trichloro­acetate anions each show one disordered Cl atom with site occupation factors of 0.945 (7):0.055 (7) 0.945 (8):0.055 (8). In the crystal, N—H⋯O, O(water)—H⋯O and O(water)—H⋯F inter­actions connect the components into a three-dimensional network.
