Abstract

Three diphosphates, α-Li₂Na₂P₂O₇, Li₈Pb₃Ba(P₂O₇)₄ and Li₇Rb(P₂O₇)₂, were synthesized via a high-temperature solution method. α-Li₂Na₂P₂O₇ crystallized into a non-centrosymmetric space group Ama2, while Li₈Pb₃Ba(P₂O₇)₄ and Li₇Rb(P₂O₇)₂ crystallized into the centrosymmetric space groups C2/c and P1respectively. α-Li₂Na₂P₂O₇, Li₈Pb₃Ba(P₂O₇)₄ and Li₇Rb(P₂O₇)₂ could be obtained by co-substitution from each other. Also, we found that the high valence state and small atomic radius of the substituted cations resulted in a larger cation-cation distance, which led to a lower dimension of the structure. Li₂Na₂P₂O₇ possessed two phases, namely, α- and β-Li₂Na₂P₂O₇, and their second harmonic generation (SHG) responses were compared. We also reported the syntheses, IR spectra, UV-vis-NIR diffuse reflectance spectroscopy data, thermal properties and first principles calculations of the title compounds.
