The asymmetric unit of the title compound, C8H14N22+·2Cl-, contains one and a half of the dications and three chloride anions. The half molecule is completed by crystallographic twofold symmetry with two C atoms lying on the rotation axis. The two ammonium groups in each cation adopt a trans conformation with respect ot the benzene ring. The ammonium groups and chloride anions are involved in the formation of a three-dimensional N-H
Cl hydrogen-bonding network, which stabilizes the crystal packing.
1,3-Phenylenedimethanamine was dissolved in ethanol, then 1N HCl was dropped to the solution. Colourless, block-like crystals of (I) suitable for X-ray data collection were obtained by slow evaporation of ethanol at 283 K.
All H atoms were initially located in a difference Fourier map. C-bound H atoms were placed in idealized positions (C—H = 0.93–0.97 Å) and refined as riding, with Uiso(H) = 1.2Ueq(C). Amino H atoms were refined with bond restraint of N—H = 0.88 (3) Å and constrained displacement parameter Uiso(H) = 1.2Ueq(N).

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 > 2sigma(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 diamine compounds are important in biologically active natural products (Pasini & Zunino, 1987; Otsuka et al., 1990), in medicinal chemistry (Michalson & Smuszkovicz, 1989; Reedijk, 1996). They are also used as chiral auxiliaries and chiral ligands in asymmetric catalysis (Blaser, 1992; Soai & Niwa, 1992; Jacobsen, 1993; Kolb et al., 1994). Herewith we present the title diamine compound, (I).
In (I) (Fig. 1), all bond lengths and angles are normal. Two amino groups in the dications adopt trans-conformation and each amino group form three N—H···Cl hydrogen bonds (Table 1) to stabilize the crystal packing.
