Effect of the Heterovalent Doping of a Cation Sublattice on Hydration and the State of Oxygen–Hydrogen Groups in Complex Oxide BaLaIn0.9M0.1O3.95 (M = Mg, Zn) with Ruddlesden–Popper Structure

Compounds BaLaInO 4 and BaLaIn 0.9 M 0.1 O 3.95 (M = Mg, Zn) with the Ruddlesden–Popper structure are synthesized. The investigated phases’ capacity for hydration is proven, with the only form of oxygen–hydrogen groups being energetically nonequivalent hydroxo groups. It is found that introducing ma...

Summary:Compounds BaLaInO 4 and BaLaIn 0.9 M 0.1 O 3.95 (M = Mg, Zn) with the Ruddlesden–Popper structure are synthesized. The investigated phases’ capacity for hydration is proven, with the only form of oxygen–hydrogen groups being energetically nonequivalent hydroxo groups. It is found that introducing magnesium and zinc raises the degree of hydration, relative to the undoped phase, and redistributes contributions from different OH − groups: the proportion of isolated OH − groups rises and the share of OH − groups that participate in strong hydrogen bonds falls.
