The asymmetric unit of the title compound {systematic name: 2-[hydroxy(6-methoxyquinolin-1-ium-4-yl)methyl]-8-vinylquinuclidin-1-ium tetrachloridozinc(II)}, (C20H26N2O2)[ZnCl4], consists of a double protonated quininium cation and a tetrachloridozinc(II) anion. The ZnII ion is in a slightly distorted tetrahedral coordination environment. The crystal structure is stabilized by intermolecular N-H
Cl and O-H
Cl hydrogen bonds.
A mixture of quinine (0.324 g, 1 mmol), ZnCl2(0.136 g, 1 mmol) and 10% aqueous HCl (6 ml) were mixed and dissolved in 20 ml water by heating to 353 K (0.5 h), forming a clear solution. The reaction mixture was cooled slowly to room temperature and crystals of the title compound were formed after 5 d.
All H atoms were placed in calculated positions, except H1, H2B, H14A and H14B, and refined using a riding model, with C—H = 0.93–0.98 Å and N—H = 0.86 Å and with Uiso(H) = 1.2(or 1.5 for methyl)Ueq(C, N). H1, H2B, H14A and H14B were located in difference Fourier maps. The coordinates of H1 atom were fixed and the Uiso(H1) parameter was refined. H2B atom was refined isotropically. H14A and H14B atoms were fixed with Uiso(H) = 1.2Ueq(C).

The existence of a chiral centre in an organic ligand is very important for the construction of noncentrosymmetric or chiral coordination polymers that exhibit desirable physical properties, such as ferroelectricity (Fu et al., 2007, 2008b) and nonlinear optical second harmonic generation (Qu et al., 2003b). Quinine has a chiral centre, which has shown tremendous scope in the synthesis of transition-metal complexes (Fu et al., 2008a; Qu et al., 2003a; Zhao et al., 2003). The construction of new members of this family of ligands is an important direction in the development of modern coordination chemistry. We report here the crystal structure of the title compound.
The asymmetric unit of the title compound consists of a double protonated quininium cation and a tetrachloridozinc anion (Fig. 1). The ZnII ion is in a slightly distorted tetrahedral coordination environment (Table 1). Intermolecular N—H···Cl and O—H···Cl hydrogen bonds lead to a one-dimensional chain along the a axis (Table 2 and Fig. 2).
