X-ray diffraction study of aqueous SrCl₂solutions

Abstract

Two aqueous solutions of SrCl2 of concentration 1.53 and 2.00 mol dm−3 have been investigated by X-ray diffraction. A model in which the Sr2+ ion was considered as having eight nearest-neighbour water molecules at a distance of 2.64 Å and a second outer shell came out in best agreement with the experimental data. Octahedral water coordination for Cl− ions has been confirmed in agreement with the results obtained by other X-ray studies.
