title: Bis(6-meth-oxy-1-methyl-2,3,4,9-tetra-hydro-1H-β-carbolin-2-ium) tetra-chloridozincate(II) dihydrate.
abstract: The asymmetric unit of the title compound, (C(13)H(17)N(2)O)(2)[ZnCl(4)]·2H(2)O, contains two tetra-hydro-harmine cations, one tetra-chloro-zincate(II) anion and two water mol-ecules. In the cations, the two 1H-indole ring systems are essentially planar, with maximum deviations of 0.016 (2) and 0.018 (2) Å, and both tetra-hydro-pyridinium rings show a half-chair conformation. The Zn(II) complex anion has a distorted tetra-hedral geometry. In the crystal, inter-molecular N-H⋯O, N-H⋯Cl, O-H⋯O, O-H⋯Cl and C-H⋯O hydrogen bonds link the components into a three-dimensional network. A π-π inter-action with a centroid-centroid distance of 3.542 (14) Å is also observed.
