Bis(6-methoxy-1-methyl-2,3,4,9-tetrahydro-1H-β-carbolin-2-ium) tetrachloridozincate(II) dihydrate
The asymmetric unit of the title compound, (C13H17N2O)2[ZnCl4]·2H2O, contains two tetrahydroharmine cations, one tetrachlorozincate(II) anion and two water molecules. 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 tetrahydropyridinium rings show a half-chair conformation. The ZnII complex anion has a distorted tetrahedral geometry. In the crystal, intermolecular N—H
O, N—HCl, O—HO, O—HCl and C—HO hydrogen bonds link the components into a three-dimensional network. A π–π interaction with a centroid–centroid distance of 3.542 (14) Å is also observed.

In the title compound, C19H21N2O2+·C2H3O2−, the 1H-indole ring system is essentially planar [maximum deviation = 0.0257 (14) Å] and forms a dihedral angle of 87.92 (7) Å with the benzene ring attached to the tetrahydropyridinium fragment. The tetrahydropyridinium ring adopts a half-chair conformation. In the crystal, cations and anions are linked by interionic N—HO, C—HO and C—HN hydrogen bonds into chains along the a axis.
