Crystal structure of 2-bromobenzoic acid at 120 K: a redetermination
The crystal structure of the title compound, C7H5BrO2, was originally studied using photographic data at room temperature with Cu Kα radiation [Ferguson & Sim (1962 ▶). Acta Cryst. 15, 346-350]. The present study was undertaken at 120 K with a CCD diffractometer using Cu Kα radiation, and resulted in improved geometrical parameters. In the mol-ecule, the carb-oxy group is inclined to the benzen...
متن کامل2,2′-Dithiodianiline: a redetermination at 100 K
STRUCTURAL STUDIES OF THE TITLE COMPOUND [SYSTEMATIC NAME: 2,2'-(disulfanedi-yl)dianiline], C(12)H(12)N(2)S(2), were previously performed at room temperature [Gomes de Mesquita (1967 ▶). Acta Cryst.23, 671; Lee & Bryant (1970 ▶). Acta Cryst. B26, 1729; Ribar et al. (1975 ▶). Bull. Yugoslav. Crystallogr. Centre, A10, 68]. The results of the current redetermination allow a clarification of the na...
متن کاملChloranilic acid: a redetermination at 100 K
The crystal structure of chloranilic acid, C(6)H(2)Cl(2)O(4), was first described by Andersen in 1967 [Andersen, E. K. (1967). Acta Cryst. 22, 188-191] at room temperature using visually estimated intensities. Taking into account the importance of the title compound, we have redetermined the structure at 100 (1) K. The approximately planar mol-ecule [the maximum deviation from the mean plane th...
متن کاملRedetermination of 3-methylisoquinoline at 150 K
The structure of the title compound, C(19)H(9)O, has been redetermined at 150 K. The redetermination is of significantly higher precision than a previous room-temperature structure [Ribar et al. (1974 ▶). Cryst. Struct. Commun.3, 323-325]. The C-N bond lengths for this redetermination are much closer to those observed in comparable structures, and the orientation of the methyl group with respec...
متن کاملRedetermination of dihydroartemisinin at 103 (2) K
Tthe structure of the title compound, C(15)H(24)O(5), has been redetermined at 103 (2) K, with much improved precision. The title compound was first reported by Luo, Yeh, Brossi, Flippen-Anderson & Gillardi [Helv. Chim. Acta (1984). 67, 1515-1522]. It is a derivative of the anti-malaria compound artemisinin and consists primarily of three substituted ring systems fused together. A cyclo-hexane ...
