In the cation of the title compound [systematic name: 3-(9H-carbazol-4-yloxy)-2-hydroxy-N-[2-(2-methoxyphenoxy)ethyl]propan-1-aminium dihydrogen phosphate hemihydrate], C24H27N2O4+·H2PO4−·0.5H2O, the mean planes of the tricyclic ring system and the benzene ring form a dihedral angle of 87.2 (2)°. In the the solvent water molecule is situated on a twofold rotation axis linking two cations via O—H⋯O and N—H⋯O hydrogen bonds. The anions contribute to the formation O—H⋯O and N—H⋯O hydrogen bonds between the anions and cations, which consolidate the crystal packing.

The title compound was synthesized in accordance with the known procedure, invented by Brook et al. (2005) for Form I.
During the exposure, the specimen was spun in its plane to improve particle statistics. The monoclinic unit-cell dimensions were determined with the indexing program ITO (Visser, 1969), M20=35, using the first 30 peak positions. The
C2/c was chosen on the basis of systematic extinction rules and confirmed later by the solution. The structure of (I) was solved by simulated annealing procedure (Zhukov et al., 2001) and refined following the methodology described in details elsewhere (Chernyshev et al., 2003) by the subsequent bond-restrained with the program MRIA (Zlokazov & Chernyshev, 1992). All non-H atoms were refined isotropically: two overall Uiso parameters were refined for the cation, and two Uiso parameters were refined for the anion - one for P and one for all O atoms. All H atoms were placed in geometrically calculated positions and not refined. The diffraction profiles and the differences between the measured and calculated profiles are shown in Fig. 2.Data collection: G670 Imaging Plate Guinier Camera Software (Huber, 2002); cell

Earlier, the crystal structures of two polymorphs of carvedilol free base have been reported (Chen et al., 1998; Yathirajan et al., 2007). Herein we report the crystal structure of the title compound (I), also known as carvedilol dihydrogen phosphate hemihydrate, Form I (Brook et al., 2005).
In (I) (Fig. 1), all bond lengths and angles in the cation are comparable with those reported earlier for two monoclinic polymorphs of carvedilol free base (Chen et al., 1998; Yathirajan et al., 2007). The mean planes of tricycle and benzene ring form a dihedral angle of 87.2 (2)°. The crystalline water molecule is situated on a twofold rotational axis linking two cations via O—H···O and N—H···O hydrogen bonds (Table 1). The anions contribute to formation O—H···O and N—H···O hydrogen bonds (Table 1) between the anions and cations giving rise to three-dimensional hydrogen-bonding network.
