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.

Tetra-methyl-ammonium dihydrogen phosphate hemihydrate.

Project description:In the crystal structure of the title compound, C(4)H(12)N(+)·H(2)PO(4) (-)·0.5H(2)O, the anions form an infinite hydrogen-bonded chain along the [10] direction. The anion chains are connected by water mol-ecules, which lie on crystallographic twofold rotation axes, through O-H?O hydrogen bonds. These hydrogen bonds are almost perpendicular to the other hydrogen bonds which create an assembled structure of anions. In addition, C-H?O hydrogen bonds between anions and cations are observed.

Dihydrogen phosphate mediated supramolecular frameworks in 2- and 4-chloroanilinium dihydrogen phosphate salts.

Project description:The title compounds, 2-chloroanilinium dihydrogen phosphate (2CADHP) and 4-chloroanilinium dihydrogen phosphate (4CADHP), both C(6)H(7)NCl(+) x H(2)PO(4)(-), form two-dimensional supramolecular organic-inorganic hybrid frameworks. In 2CADHP, the dihydrogen phosphate anions form a double-stranded anionic chain generated parallel to the [010] direction through O-H...O hydrogen bonds, whereas in 4CADHP they form a two-dimensional supramolecular net extending parallel to the crystallographic (001) plane into which the cations are linked through strong N-H...O hydrogen bonds.

2-Amino-pyrimidinium dihydrogen phosphate monohydrate.

Project description:In the title compound, C(4)H(6)N(3) (+)·H(2)O(4)P(-)·H(2)O, the pyrimidin-ium ring is essentially planar, with an r.m.s. deviation of 0.0016 Å. In the structure, pairs of symmetry-related anions are connected into centrosymmetric clusters via strong O-H⋯O hydrogen bonds forming six-membered rings with an R(2) (2)(6) motif. These clusters are inter-connected via water mol-ecules through OW-H⋯O hydrogen bonds, building an infinite layer parallel to the ab plane. Moreover, infinite chains of 2-amino-pyrimidinium cations spread along the a-axis direction. These chains are connected to the inorganic layer through N-H⋯O, C-H⋯O and C-H⋯N hydrogen bonds, which, together with electrostatic and van der Waals inter-actions, contribute to the cohesion and stability of the network in the crystal structure.
