In the title salt adduct, C(17)H(21)ClN(2) (2+)·2C(2)Cl(3)O(2) (-)·C(2)HCl(3)O(2), the Cl atom of the dication is disordered over two positions in a 0.915 (3):0.085 (3) ratio. The Cl atoms in the trichloroacetate anions and trichloroacetic acid molecule are also disordered, with refined site-occupation factors of 0.59 (3):0.41 (3), 0.503 (12):0.417 (12) and 0.653 (12):0.347 (12). The piperazine ring adopts a chair conformation, with puckering parameters Q(T) = 0.587 (3) Å, θ = 2.6 (2) and Φ 334 (6)°. In the crystal, neighbouring mol-ecules are linked by N-H⋯O, O-H⋯O, N-H⋯Cl, C-H⋯O and C-H⋯Cl hydrogen bonds, forming a three-dimensional network.
在标题盐加合物C(17)H(21)ClN(2) (2+)·2C(2)Cl(3)O(2) (-)·C(2)HCl(3)O(2)中，二价阳离子的Cl原子在两个位置上无序，比例为0.915 (3):0.085 (3)。三氯乙酸根阴离子和三氯乙酸分子中的Cl原子也无序，精修的位点占有率因子分别为0.59 (3):0.41 (3)、0.503 (12):0.417 (12)和0.653 (12):0.347 (12)。哌嗪环呈椅式构象，褶皱参数Q(T) = 0.587 (3) Å，θ = 2.6 (2)，Φ 334 (6)°。在晶体中，相邻分子通过N-H⋯O、O-H⋯O、N-H⋯Cl、C-H⋯O和C-H⋯Cl氢键相连，形成三维网络。
