Redetermination of loperamide monohydrate
The structure of the title compound {systematic name: 4-[4-(4-chloro-phen-yl)-4-hy-droxy-piperidin-1-yl]-N,N-dimethyl-2,2-di-phenyl-butanamide monohydrate}, C(29)H(33)ClN(2)O(2)·H(2)O, has been redetermined at 170 (2) K. The redetermination is of significantly higher precision than the previous structure determination at room temperature and includes the H-atom coordinates that were not include...
متن کاملRedetermination of orotic acid monohydrate
The crystal structure of the title compound, which is also known as vitamin B(13) (systematic name: 2,6-dioxo-1,2,3,6-tetra-hydro-pyrimidine-4-carboxylic acid monohydrate), C(5)H(4)N(2)O(4)·H(2)O, was reported for the first time by Takusagawa & Shimada [Bull. Chem. Soc. Jpn (1973 ▶), 46, 2011-2019]. The present redetermination provides more precise values of the mol-ecular geometry. The asymmet...
متن کاملRedetermination of dipotassium trichloridostannate(II) chloride monohydrate
The title compound, K(2)[SnCl(3)]Cl·H(2)O, is the prototype of some isostructural compounds of composition M(2)[SnX(3)]X·H(2)O (M = large monovalent cation; X = halogen). In comparison with a previous study based on photographic data [Kamenar & Grdenić (1962 ▶). J. Inorg. Nucl. Chem.24, 1039-1045], its crystal structure has now been redetermined using CCD-based data in order to gain more accura...
متن کاملRedetermination of ethylenediammonium bis(p-methylbenzenesulfonate) monohydrate
In the asymmetric unit of the title compound, C(2)H(10)N(2) (2+)·2C(7)H(7)O(3)S(-)·H(2)O, there are two independent 4-methyl-benzene-sulfonate anions, one ethyl-enediammonium cation and a water mol-ecule. The present redetermination was carried out to improve the treatment of disorder, which was not refined in the previous study [Ahn & Kim (1985 ▶). J. Korean Chem. Soc.29, 335-340]. One of the ...
متن کاملRedetermination and absolute configuration of pruniflorone M monohydrate
THE TITLE XANTHONE KNOWN AS PRUNIFLORONE M (SYSTEMATIC NAME: (2R)-5,10-dihy-droxy-2-hy-droxy-methyl-1,1-dimethyl-1H-furo[2,3-c]xanthen-6-one), crystallized in a monohydrate form, C(18)H(16)O(6)·H(2)O. It was isolated from the green fruits of Cratoxylum formosum ssp. pruniflorum. The structure of the title compound has been reported previously [Boonnak et al. (2010 ▶). Aust. J. Chem. 63, 1550-15...
