A mixture of quinine (1 mmol, 0.324 g ), FeCl3(1 mmol, 0.156 g) 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, crystals of the title compound were formed after 11 days.
All H atoms of quinine were placed in calculated positions , with C—H = 0.93-0.98 Å O—H = 0.85 Å and N—H = 0.96 Å, and re?ned using a riding model, with Uiso(H)=1.2Ueq(C, N, O) or 1.5 Ueq(C) for methyl H atoms.H3A and H3B were located in difference fourier maps.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The existence of a chiral centre in an organic ligand is very important for the construction noncentrosymmetric or chiral coordination polymers that exhibit desirable physical properties such as ferroelectricity (Fu et al., 2007), Chiral quinine has a chiral centre which have shown tremendous scope in the synthesis of transition-metal complexes (Zhao et al., 2003; Qu 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,C20H26N2O2.FeCl4.Cl.H2O(Fig.1), consists of one protoned quinine and a tetrachloro-ironanion with the FeIII ion in a slightly distorted tetrahedral coordination environment, The crystal structure is stabilized by intermolecular N—H···Cl, O—H···Cl and O—H···O hydrogen bonds.The H-bonds form of1D chain viewedalong the a-axis (Fig.2).
