Abstract

Two new mixed-anion cerium iodates, namely, Ce(IO₃)₃F and Ce(IO₃)₂(NO₃), have been rationally designed through the integration of hybrid anionic functional building blocks (FBBs). The structure of Ce(IO₃)₃F features a novel [Ce(IO₃)₃F] bilayer, and the material exhibits large birefringence (0.225 @546 nm). The structure of Ce(IO₃)₂(NO₃) features [Ce₃(IO₃)₆]³⁺ triple layers that are further linked by planar NO₃^- units. Ce(IO₃)₂(NO₃) shows a moderate SHG response (1 × KDP) and a high laser-induced damage threshold value (22 × AgGaS₂). This work demonstrates that the rich coordination geometries of cerium cations facilitate tuning of the structures of related compounds through modulating anionic FBBs.
