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 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 کاملCrystal structure of K[Hg(SCN)3] – a redetermination
The crystal structure of the room-temperature modification of K[Hg(SCN)3], potassium tri-thio-cyanato-mercurate(II), was redetermined based on modern CCD data. In comparison with the previous report [Zhdanov & Sanadze (1952 ▶). Zh. Fiz. Khim. 26, 469-478], reliability factors, standard deviations of lattice parameters and atomic coordinates, as well as anisotropic displacement parameters, were ...
متن کاملCrystal Structure of Nonaaquayttrium(III) Bromate at 100 K
The structure of the nonaaquayttrium (III) bromate, [Y(H2O)9](BrO3)3, at low temperature (100 K) has been studied by means of single-crystal X-ray diffraction. Crystallography shows a hexagonal unit cell, space group P63/mmc (No. 194) with Z = 2, a = b = 11.7104(11) Å, c = 6.6259(5) Å and V = 786.90(12) Å3 at 100 K. The hydra...
متن کاملRedetermination of Crystal Structure of N,N'-bis (2-Hydroxybenzylidene)-2,2-Dimethyl-1,3-Propanediamine
The structure of N,N'-bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine, C19H22N2O2, has been studied at low temperature (120K) by means of single-crystal X-ray diffraction. Solving the structure shows an orthorhombic unit cell, with P212121 space group, Z = 4, a = 6.1046 (4) Å, b = 15.8349 (11)</e...
