Comment top

The crystal structures of two polymorphs of carvedilol free base (Chen et al., 1998; Yathirajan et al., 2007) and carvedilol dihydrogen phosphate hemihydrate Form I (Chernyshev et al., 2009) were recently reported. As a contribution to structural study of carvedilol, herewith we report the crystal structure of the title compound (I) (Fig. 1).

One of two amino H atoms (H19B) is involved in intramolecular N—H···O hydrogen bonds (Table 1), which influence the cation conformation. The mean planes of the tricyclic carbazole system and the benzene ring form a dihedral angle of 42.00 (16)°. In the crystal structure, the classical intermolecular O—H···O and N—H···O hydrogen bonds (Table 1) link cations, anions and solvent molecules into layers parallel to the ac plane.

Experimental top

Carvedilol dihydrogen phosphate hemihydrate (CDPH) was synthesized in accordance with the known procedure (Brook et al., 2005). Synthesis of carvedilol dihydrogen phosphate isopropanol solvate was carried out under stirring in round bottom four necked flask (0.5 L) equipped with thermometer and heated addition funnel. A hot solution (55-60°C) of CDPH (4 g, 8 mmol) in MeOH (70 ml) was placed in heated (60°C) addition funnel. Then this solution was added dropwise to isopropanol (250 ml) for 40 minutes at -20°C. The mixture was left to stand at -17°C for 20 h. The precipitate was filtered on suction funnel, washed with cooled (10°C) isopropanol (20 ml) and then dried under vacuum at 45°C for 17 h. Carvedilol dihydrogen phosphate isopropanol solvate (3.8 g, yield 95%) was obtained with purity of 99.8 % (measured with HPLC). IR-spectrum is shown on Fig. 2.

Refinement top

During the exposure, the specimen was spun in its plane to improve particle statistics. The triclinic unit cell dimensions were determined with the indexing program TREOR (Werner et al., 1985), M20 = 43, using the first 30 peak positions. The structure of (I) was solved by simulated annealing procedure (Zhukov et al., 2001) and refined following the methodology described in (Chernyshev et al., 2009). All non-H atoms were isotropically refined. H atoms were placed in geometrically calculated positions (O—H 0.82 Å; N—H 0.86–0.90 Å; C—H 0.93–0.98 Å) and included in the refinement in riding motion approximation [Uiso(H) = 1.2Ueq of the carrying atom (1.5Ueq for O-H and Me groups)]. The diffraction profiles and the differences between the measured and calculated profiles are shown in Fig. 3.

Special details top

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.
