Structure description
Histamine is a biologically important compound in the body's immune system (Schneider et al., 2014). It contains an imidazole group which is a nitrogenous aromatic compound found in enzymes and in various drugs (Zlomuzica et al., 2016). Histamines are of interest spanning a wide variety of topics, including drug therapeutics (Zlomuzica et al., 2016), cancer (Martinel Lamas et al., 2015), addictions (Nuutinen et al., 2016), and autoimmune (Abiuso et al., 2014) and anxiety disorders (Cacabelos et al., 2016). In view of this interest in histamine, several structures of histamine salts have been determined through X-ray crystallography previously containing both histamine dications (Veidis et al., 1969; Yamane et al., 1973) and histamine cations (Prout et al., 1974; Belfilali et al., 2015).
The present report contains the structure of the perchlorate salt of histamine in the diprotonated form, which crystallizes in the monoclinic P21/c with two formula units in the (Fig. 1). One of the histamine dications is disordered [occupancies of 0.718 (4) and 0.282 (4)] and two of the four perchlorate anions are disordered [occupancies of 0.735 (6):0.265 (6) and 0.637 (5):0.363 (5)]. The metrical parameters of the diprotonated imidazolium ring are similar to those found for the phosphate (Veidis et al., 1969) and sulfate analogs (Yamane et al., 1973). It has been suggested (Kier, 1968) that the dual activity of histamine is a consequence of the ability of its monocation to adopt two distinct preferred conformations, viz. trans and gauche rotamers involving the ethanamine substituent. In the title compound, there are two independent histamine dications and one of them is disordered over two conformations. The three C3—C4—C5—N3 torsion angles are −64.3 (5), 59.4 (7), and −50 (2)°. These values are in contrast to the values reported in the two structures containing histamine cations where these torsion angles are 177.3 (Prout et al., 1974) and 176.22 (10)° (Belfilali et al., 2015).
There is extensive hydrogen bonding in the structure, involving both N—H⋯O and C—H⋯O interactions, which link the histamine dications and perchlorate anions into a three-dimensional array (Table 1 and Fig. 2).
Synthesis and crystallization
Histamine hydrochloride (0.3181 g, 1.728 mmol) was dissolved in 15 ml of methanol. Zn(ClO4)2·6H2O (0.6434 g, 1.728 mmol) was dissolved in 15 ml of methanol and added to the histamine hydrochloride solution. The mixture was stirred at room temperature overnight. The methanol was removed by rotary evaporation. The product was crystallized by redissolving it in acetonitrile and layering the solution with diethyl ether. After ∼1 h, a colorless crystal formed. The crystal was allowed to grow overnight before gravity filtration, air drying, and collection of the crystallized product for XRD analysis.
Refinement
Crystal data, data collection and structure . One of the histamine dications is disordered [occupancies of 0.718 (4) and 0.282 (4)] and both components were constrained to have similar metrical parameters. Two of the four perchlorate anions are also disordered [occupancies of 0.735 (6):0.265 (6) and 0.637 (5):0.363 (5)] and were constrained to be tetrahedral.

All of the H atoms were placed in calculated positions and then refined using the riding model, with C/N—H = 0.95 (CH), 0.88 (NH), 0.99 (CH2), or 0.91 Å (NH3). Isotropic displacement parameters for these atoms were set at 1.2 (CH, NH and CH2) or 1.5 (NH3) times Ueq of the parent atom. The H atoms for the idealized ammonium groups were refined as rotating groups.

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. |
