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 کاملCrystal structure of lead tungstate at 1.4 and 300 K
The crystal structure of lead tungstate, PbWO4, is tetragonal, scheelite type, space group I41/a. This compound is frequently subjected to lead deficiency, due to the difference in the vapour pressure of the two oxides, WO3 and PbO, used in the crystal growth. One group has reported that lead vacancies can order in a crystal structure derived from the scheelite type, but of lower symmetry and d...
متن کاملCrystal structure of cholesteryl butanoate at 123 K ' Gye
Cholesteryl butanoate has a complex crystal structure that differs from those of the three main structure types for cholesteryl esters. It contains four molecules (C3LH5202) unrelated by crystal symmetry. The molecules are packed in almost planar sheets and have molecular long axes nearly parallel. However, the molecules have different orientations about their long axes and furthermore, in a gi...
متن کاملCrystal structure of allylammonium hydrogen succinate at 100 K
The asymmetric unit of the title compound, C2H8N(+)·C4H5O4 (-), consists of two allyl-ammonium cations and two hydrogen succinate anions (Z' = 2). One of the cations has a near-perfect syn-periplanar (cis) conformation with an N-C-C-C torsion angle of 0.4 (3)°, while the other is characterized by a gauche conformation and a torsion angle of 102.5 (3)°. Regarding the anions, three out of four ca...
