Tuberostemoamide hemihydrate
In the crystal structure of the title compound {systematic name: (1'S,2R,2'R,3'S,6'R)-3'-ethyl-4-methyl-5H-5'-oxa-10'-aza-spiro-[furan-2,4'-tricyclo-[8.3.0.0(2,6)]trideca-ne]-5,11'-dione hemihydrate}, C(17)H(23)NO(4)·0.5H(2)O, the asymmetric unit contains two mol-ecules of tuberostemoamide with similar conformations and one water mol-ecule. The tuberostemoamide mol-ecule is composed of one seve...
متن کاملDiosgenin hemihydrate
Diosgenin [or (22R,25R)-spirost-5-en-3β-ol] is the starting material of the Marker degradation, a cheap semi-synthesis of progesterone, which has been designated as an Inter-national Historic Chemical Landmark. Thus far, a single X-ray structure for diosgenin is known, namely its dimethyl sulfoxide solvate [Zhang et al. (2005 ▶). Acta Cryst. E61, o2324-o2325]. We have now determined the structu...
متن کامل5-Bromophthalazine hemihydrate
The title compound, C(8)H(5)BrN(2)·0.5H(2)O, is a phthalazine derivative synthesized from 3-bromo-benzene-1,2-dicarbaldehyde and hydrazine. The mol-ecule is essentially planar, the deviation from the mean plane of the phthalazine ring being 0.015 (3) Å. The O atom of the solvent water mol-ecule is situated on a twofold rotation axis. In the crystal, O-H⋯N hydrogen bonds and short N⋯Br [2.980 (3...
متن کامل4-Phenethoxyaniline hemihydrate
The crystal structure of the title compound, C(14)H(15)NO·0.5H(2)O, features N-H⋯O and O-H⋯N hydrogen bonds between the amino group and water molecule of crystallization, which generate a chain along the c axis. The water mol-ecule lies on a twofold rotation axis. A C-H⋯π inter-action is observed between the phenyl and aniline rings. The angle between the mean planes of the phenyl rings is 72.5...
متن کامل4-Carbamoylpiperidinium phenylacetate hemihydrate
The asymmetric unit of the title compound, C(6)H(13)N(2)O(+)·C(8)H(7)O(2) (-)·0.5H(2)O, comprises two isonipecotamide cations, two phenyl-acetate anions and a water mol-ecule of solvation. The hydrogen-bonding environments for both sets of ion pairs are essentially identical with the piperidinium and amide 'ends' of each cation involved in lateral heteromolecular hydrogen-bonded cyclic N-H⋯O as...
