Redetermination 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 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 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 کاملOrotic acid in milk.
Other studies in this laboratory (1) drew our attention to the possibility that erotic acid might be concerned with the maintenance of adequate lactation in the rat and with the survival of the young. Since no data were available on the erotic acid content of milk, this study was undertaken. The occurrence of erotic acid as a component of milk has been indicated since 1904, when Biscaro and Bel...
