title: 4-(4-Chloro-phen-yl)-4-hy-droxy-piperidinium maleate maleic acid solvate.
abstract: In the cation of the title compound, C(11)H(15)ClNO(+)·C(4)H(3)O(4) (-)·C(4)H(4)O(4), the dihedral angle between the mean planes of the chlorine-substituted aromatic ring and the 4-hy-droxy-piperidinium ring (C-C-C-C-C-N) is 61.9 (8)°. Intra-molecular O-H⋯O and inter-molecular O-H⋯O and N-H⋯O hydrogen bonding, as well as weak π-stacking inter-actions [centroid-centroid distance = 3.646 (5) Å] help to establish the packing.
