(Received 17 May 2010; accepted 1 September 2010; online 4 September 2010)

In the cation of the title compound [systematic name: 1-(3-cyclo­hexyl-3-hy­droxy-3-phenyl­prop­yl)piperidinium chloride], C20H32NO+·Cl, the cyclo­hexyl and piperidine rings are in chair conformations. In the crystal structure, cations and anions are linked into chains along the c-axis direction via O—H⋯Cl and N—H⋯Cl hydrogen bonds. Weak inter­molecular C—H⋯Cl inter­actions link further these chains into layers parallel to the bc plane. The salt, obtained from a racemic solution, was found to crystallize in the chiral P21212 space group, indicating that, in the absence of any evident chirality-inducing process, the polycrystalline powders consist of an equivalent mixture of R and S enanti­omers, forming a racemic conglomerate.

Comment top

The title compound, THPD-HCl (THPD = trihexyphenidyl) (1), crystallizes in the non-centrosymmetric space group P21212, thus powders of 1 are formed by an equivalent mixture of enantiomorphic crystals in a racemic conglomerate. 1 consists of an ionic packing of N-protonated cations and chloride anions. The organic cation is formed by a phenyl and a cyclohexyl groups connected to the asymmetric carbon atom (C3) which is further linked to an hydroxyl group and to a protonated N-ethyl piperidine moiety (see Fig. 1). Trihexyphenidyl hydrochloride (1), is a salt used in the treatment of all forms of Parkinson's disease. Trihexyphenidyl and other pharmacological agents of the same class, such as procyclidine hydrochloride and biperiden, were completely characterized by single-crystal X-ray analyses (Camerman & Camerman, 1971a, 1972a; Codding, 1986; Marubayashi et al., 1999), which showed some common stereochemical features which were correlated to their common pharmacological activity. The presence of the electron donating OH group and of the heterocyclic nitrogen has been considered as the typical stereochemical feature of these compounds.The distance between the two groups is 4.00 Å, 2.76 Å and 3.55 Å for 1, THPD, biperiden and procyclidine hydrochloride, in sequence. The shorter N—O distance observed in THPD allows the formation of intramolecular hydrogen bonds O—H···N. At variance, 1 and procyclidine hydrochloride form intermolecular hydrogen bonds through chloride anions. In the crystal, the NH group is pointing away from the direction of the OH group, allowing the formation of molecular chains running along the c axis, through intermolecular O—H···Cl and N—H···Cl hydrogen bonds (Table 1). Moreover, weaker C—H···Cl interactions (Table 1) link the chains in a three-dimensional network.

Refinement top

Approximate cell parameters for 1 were determined by the SVD indexing algorithm present in the program TOPAS-R (Coelho, 2005), using the first 20 peak positions, M(20) = 31. Structure solution was initiated by employing a semi-rigid molecular fragment (flexible about five torsion angles) taken from the known crystal structure of THPD (see Camerman & Camerman 1972a) and a freely floating Cl- anion. Simulated annealing allowed the location and orientation of the used fragments, later refined by the Rietveld method, using the independent atom model for non-H atoms (geometrically restrained to achieve convergence to a chemically plausible structure) and idealized H-atom positions. The diffraction profile and the difference between the measured and calculated profiles are shown in Fig. 3.
