In the title mol­ecular salt [systematic name: (5α,6α)-7,8-didehydro-4,5-ep­oxy-17-methyl­morphinan-3,6-diol hydro­chloride], C17H20NO3+·Cl, the conformation of the morphinium ion is in agreement with the characteristics of the previously reported morphine forms [for example, Gylbert (1973[Gylbert, L. (1973). Acta Cryst. B29, 1630-1635.]). Acta Cryst. B29, 1630–1635]. In the crystal, the cations and chloride anions are linked into a helical chain propagating parallel to the b-axis direction by N—H⋯Cl and O—H⋯Cl hydrogen bonds. The title salt and the morphine monohydrate [Bye (1976[Bye, E. (1976). Acta Chem. Scand. Ser. B, 30, 549-554.]) Acta Chem. Scand. 30, 549–554] display very similar one-dimensional packing modes of their morphine components.

Comment top

Morphine is the principal alkaloid of opium. Several crystal forms of the free base as well as salts have been investigated in previous studies: a monohydrate (Bye, 1976), a hydrochloride trihydrate (Gylbert, 1973), a hydroiodide dihydrate (Mackay & Hodgkin, 1955), a complex with β–phenylhydracrylic acid (Lutz & Spek, 1998) and a bis(morphininium) dihydrogensulfate pentahydrate (Wongweichintana et al., 1984). The crystal structure of the title salt was previously solved from powder data by Guguta et al. (2008). However, the corresponding atomic coordinates are not available from the Cambridge Structural Database (Allen, 2002) or from supplementary materials accompanying this report.

The asymmetric unit of the title salt contains of one formula unit (Figure 1). The geometry of the molecular morphine scaffold with its five rings agrees with the characteristics of the previously investigated salt and free base structures. The morphinium cation of the title salt is doubly O—H···Cl bonded to the anion so that a R12(10) ring (Etter et al., 1990; Bernstein et al., 1995) is formed. The Cl- ion is additionally N—H···Cl bonded to the protonation site of a second cation, which is related to the first cation by a 21 screw operation parallel to the b–axis. An infinite hydrogen–bonded chain is formed as a result of these interactions, and the chain structure propagates parallel to the b-axis (Figure 2a). The closest intermolecular C—H···O and C—H···π contacts are listed in Table 2 and shown in Figure 2 b.

The program XPac (Gelbrich & Hursthouse, 2005) was used to compare the packing of the morphinium ions with that of the analogous moieties in the five related structures mentioned above (Bye, 1976; Gylbert, 1973; Mackay & Hodgkin, 1955; Lutz & Spek, 1998; Wongweichintana et al., 1984). In this group, the closest similarity relationship involving the title structure is based on a single stack of molecules ('one–dimensional supramolecular construct', Figure 3) that is also present in the monohydrate (Bye, 1976). In both crystals the corresponding stacking vector lies parallel [100] with d = 7.359 Å for the title structure and d = 7.438 Å for the monohydrate. The corresponding XPac dissimilarity index x (Gelbrich et al., 2012) is 8.2, calculated for a cluster comprising a central molecule and its two next neighbours in the stack on the basis of the positions of all 21 non–H atoms. This value confirms that the fundamental geometry of the stack is maintained. However, the geometry of the stack is somewhat affected by its crystal environment, which accomodates the specific hydrogen bond preferences of the second chemical component, i.e. Cl- in the case of the title structure and H2O in the monohydrate.

Experimental top

The investigated compound was obtained from Heilmittelwerke Wien, Austria. Block-shaped crystals of the title compound were produced by slow evaporation from an ethanol solution.

Refinement top

The H atoms were identified in a difference map. Methyl H atoms were idealized and included as rigid groups allowed to rotate but not tip (C—H = 0.98 Å). H atoms bonded to tertiary CH (C—H = 0.99 Å), secondary CH2 (C—H = 0.99 Å) and aromatic carbon atoms (C—H = 0.95 Å) were positioned geometrically. Hydrogen atoms attached to O and N atoms were refined with restrained distances [O—H = 0.82 (1) Å] and [N—H = 0.93 (1) Å]. The parameters Uiso of all H atoms were refined freely.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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.
