The crystal structure of barium hydroxide octahydrate Ba(OH)2·8H2O*
Abstract
An x-ray analysis of the crystal structure of barium hydroxide octahydrate has been carried out by two-dimensional Fourier methods. The monoclinic crystals belong to the space group P21/n and have four formula units in a cell of dimensions a = 9.35 Å, b = 9.28 Å, c = 11.87 Å with β = 99°. The R factor for 1020 visually observed reflections in eight zones is 0.124. The barium ion in this structure is found to be coordinated by eight water oxygens in the form of a slightly distorted Archimedean antiprism at distances between 2,69 Å and 2.77 Å. Based on the interatomic distances hydrogen bonds have been proposed, which link the oxygen atoms with one another utilising all the hydrogen atoms in the unit cell.
