Abstract
Conditions to obtain two polymorphic forms by crystallization from solution were determined for the analgesic drug hydromorphone [C17H19NO3; systematic name: (4R,4aR,7aR,12bS)-9-hydroxy-3-methyl-1,2,4,4a,5,6,7a,13-octahydro-4,12-methanobenzofuro[3,2-e]isoquinolin-7-one]. These two crystalline forms, designated as I and II, belong to the P212121 orthorhombic space group. In both polymorphs, the hydromorphone molecules adopt very similar conformations with some small differences observed only in the N-methyl amine part of the molecule. The crystal structures of both polymorphs feature chains of molecules connected by hydrogen bonds; however, in form I this interaction occurs between the hydroxyl group and the tertiary amine N atom whereas in form II the hydroxyl group acts as a donor of a hydrogen bond to the O atom from the cyclic ether part.
Chemical context
Drug polymorphism has been the subject of hundreds of publications and numerous excellent reviews (Byrn et al., 1999 ▸; Grant, 1999 ▸; Singhal & Curatolo, 2004 ▸; Vippagunta et al., 2001 ▸). It is well established that polymorphs with different stability may have different solubility and dissolution rates, which can affect the bioavailability. The semi-synthetic opiate drug hydromorphone is a potent derivative of morphine and despite poor bioavailability (Parab et al., 1988 ▸) is commonly used to treat moderate to severe pain in the treatment of cancer (Sarhill et al., 2001 ▸). To improve bioavailability of this compound a polymorph screen was performed that resulted in two solvent-free forms, designated as form I and form II.
Structural commentary
The molecular structure of hydromorphone in both polymorphs is nearly identical (Fig. 1 ▸) with some deviations found only for the N-methyl amine part of the piperidine fragment (Fig. 2 ▸). For example the C10—C11—N12—C13 torsion angle is 178.5 (2)° for form I and 169.5 (2)° for form II. The adopted conformation is similar to the conformation observed for morphine (Bye, 1976 ▸; Scheins et al., 2005 ▸).

Supramolecular features
Although both polymorphs crystallize in the same space group P212121 with the same number of molecules in the asymmetric unit, they differ significantly in the packing features (Figs. 3 ▸ and 4 ▸). In form I, the hydrogen-bonded molecules are arranged into chains that run along the a axis with adjacent molecules in the chain related by translation. The hydroxyl group donates a hydrogen atom which is accepted by the free electron pair of the N atom (Fig. 5 ▸, Table 1 ▸). In the crystals of form II, intermolecular hydrogen bonds also generate a chain of molecules that propagates along the a axis; however, adjacent molecules along this chain are related by a 21 symmetry axis. The molecules are connected by O—H⋯O hydrogen bonds with the hydroxyl group as donor and the etheric O atom as acceptor (Table 2 ▸). These chains form a zigzag pattern, as illustrated in Fig. 6 ▸. The packing arrangement of molecules in form II is more dense than in polymorph I, as indicated by the Kitajgorodskij (1973 ▸) packing coefficients of 0.71 and 0.69, respectively.

Synthesis and crystallization
10.8 mg of hydromorphone was dissolved in 1.8 mL THF/acetone (1/1, v/v) and left to evaporate slowly under ambient conditions. After several days, colorless prism-like crystals of form I (m.p. 549.8 K) appeared that were used for diffraction studies. Crystals of form II were obtained in the following way: 19.7 mg of hydromorphone was suspended in 0.3 mL of 50/50 mixture of ethanol and toluene. The suspension was heated to 333 K and stirred for about one h until it became clear. Subsequently, the vial was cooled rapidly to 278 K and colorless block-like crystals (m.p. 550.2 K) precipitated that were used for diffraction studies.
Refinement
The H atoms from the methyl group in form II were included from geometry and their isotropic displacement parameters refined. The remaining H atoms were found in a Fourier difference map and freely refined. The absolute configuration of hydromorphone was known from the synthetic route. In the absence of significant anomalous scattering effects, Friedel pairs were merged. Crystal data, data collection and structure refinement details are summarized in Table 3 ▸.

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. |

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. |
