Description
Summary:Phosphite materials have aroused wide attention due to their diverse open frameworks and promising magnetic and optical performances. Here, the first barium scandium phosphite, BaSc2(HPO3)4(H2O)2, was obtained via a facile hydrothermal route. BaSc2(HPO3)4(H2O)2 crystallizes in the polar space group Pn and exhibits a 3D {[Sc2(HPO3)4]2−}∞ anion framework constructed by distorted ScO6 octahedra and HPO32− anion groups. BaSc2(HPO3)4(H2O)2 can exhibit a phase-matchable SHG response of about 0.94 × KH2PO4 at 1064 nm, and a moderate birefringence (0.036@1064 nm) to satisfy the phase-matchable behavior requirement. Deep investigation of its structure–property relationship based on theoretical calculations has also been presented in this work.
