The Influence of the Nature of Halogen on the Local Structure and Intercalation of Water in Oxyhalides Ba2InO3X (X = F, Cl, Br)

Abstract

Oxyhalides Ba2InO3F, Ba2InO3Cl, and Ba2InO3Br are synthesized, and their phase homogeneity is confirmed by the method of X-ray diffraction. The influence of the nature of a halide ion on the crystal-lattice parameters and on the In–O bond lengths is established. The ability of the studied phases to undergo hydration and formation of oxygen–hydrogen groups in their structure is proven.
