Crystal 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 کاملDimethyl 4,4′-(diazenediyl)dibenzoate at 100 K
In the asymmetric part of the unit cell of the title compound, C16H14N2O4, there are two chemically equivalent but crystallographic independent half mol-ecules. The geometric centre of each complete mol-ecule lies on a crystallographic inversion centre. Both mol-ecules are almost planar [mean deviations of atoms in the two molecules are 0.032 (2) and 0.044 (2) Å] and their geometries are simila...
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 کاملSBN60, strontium-barium niobate at 100 K
The title compound, Sr0.6Ba0.4Nb2O6 (strontium barium niobium oxide), belongs to the group of strontium-barium niobates with varying composition of Sr and Ba. Their general formula can be written as Sr x Ba1 - x Nb2O6. Below the Curie temperature, T c , these materials indicate ferroelectric properties. The Curie temperature for SBN60 is equal to 346±0.5 K so the structure is in the ferroelectr...
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...
