Crystal structure of canagliflozin hemihydrate
There are two canagliflozin mol-ecules (A and B) and one water mol-ecule in the asymmetric unit of the title compound, C24H25FO5S·0.5H2O [systematic name: (2S,3R,4R,5S,6R)-2-(3-{[5-(4-fluoro-phen-yl)thio-phen-2-yl]meth-yl}-4-methylphen-yl)-6-(hy-droxy-meth-yl)-3,4,5,6-tetra-hydro-2H-pyran-3,4,5-triol hemihydrate]. The dihedral angles between the methyl-benzene and thio-phene rings are 115.7 (4)...
متن کاملCrystal structure of isobutylammonium hydrogen oxalate hemihydrate
In the title hydrated mol-ecular salt, C4H12N(+)·C2HO4 (-)·0.5H2O, the O atom of the water mol-ecule lies on a crystallographic twofold axis. The dihedral angle between the CO2 and CO2H planes of the anion is 18.47 (8)°. In the crystal, the anions are connected to each other by strong near-linear O-H⋯O hydrogen bonds. The water mol-ecules are located between the chains of anions and iso-butyl-a...
متن کاملCrystal structure of 4-formylpyridine semicarbazone hemihydrate
The mol-ecule of the title compound C7H8N4O·0.5H2O, alternatively called (E)-1-(pyridin-4-yl-methyl-ene)semi-carb-azide hemihydrate, is in the E conformation and is almost planar; the r.m.s. deviation of the positions of the atoms of the pyridine ring from the best-fit plane is 0.0039 Å. The C, N and O atoms of the rest of the mol-ecule sits close on this plane with a largest deviation of 0.115...
متن کاملCrystal structure of 3-methylpyridinium picrate: a triclinic polymorph
The title mol-ecular salt, C6H8N(+)·C6H2N3O7 (-) (systematic name: 3-methyl-pyridinium 2,4,6-tri-nitro-phenolate), crystallizes in the triclinic space group P-1. The crystal structure of the monoclinic polymorph (space group P21/n) has been reported [Stilinovic & Kaitner (2011 ▸). Cryst. Growth Des. 11, 4110-4119]. In the crystal, the anion and cation are linked via bifurcated N-H⋯(O,O) hydroge...
متن کاملCrystal structure of 2,6-dimethyl-4-pyridone hemihydrate
The title compound (systematic name: 2,6-dimethyl-1H-pyridin-4-one hemihydrate), C7H9NO·0.5H2O, has a single planar mol-ecule in the asymmetric unit with the non-H atoms possessing a mean deviation from planarity of 0.021 Å. There is also half of a water mol-ecule present in the asymmetric unit. In the crystal, infinite (001) sheets are formed by N-H⋯O and O-H⋯O hydrogen bonds.
