Carvedilol dihydrogen phosphate hemihydrate: a powder study

Abstract

IN THE CATION OF THE TITLE COMPOUND [SYSTEMATIC NAME: 3-(9H-carbazol-4-yl-oxy)-2-hydr-oxy-N-[2-(2-methoxy-phen-oxy)eth-yl]propan-1-aminium dihydrogen phosphate hemihydrate], C(24)H(27)N(2)O(4) (+)·H(2)PO(4) (-)·0.5H(2)O, the mean planes of the tricyclic ring system and the benzene ring form a dihedral angle of 87.2 (2)°. In the crystal structure, the solvent water mol-ecule 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.
