Two new mixed-anion cerium iodates, namely, Ce(IO)F and Ce(IO)(NO), have been rationally designed through the integration of hybrid anionic functional building blocks (FBBs). The structure of Ce(IO)F features a novel [Ce(IO)F] bilayer, and the material exhibits large birefringence (0.225 @546 nm). The structure of Ce(IO)(NO) features [Ce(IO)] triple layers that are further linked by planar NO units. Ce(IO)(NO) shows a moderate SHG response (1 × KDP) and a high laser-induced damage threshold value (22 × AgGaS). This work demonstrates that the rich coordination geometries of cerium cations facilitate tuning of the structures of related compounds through modulating anionic FBBs.
通过整合混合阴离子功能结构单元（FBBs），合理设计了两种新型混合阴离子碘酸铈，即Ce(IO)F和Ce(IO)(NO)。Ce(IO)F的结构具有新颖的[Ce(IO)F]双层结构，该材料表现出较大的双折射（在546nm处为0.225）。Ce(IO)(NO)的结构具有[Ce(IO)]三层结构，这些三层结构通过平面NO单元进一步连接。Ce(IO)(NO)表现出中等的二次谐波响应（1×KDP）和较高的激光损伤阈值（22×AgGaS）。这项工作表明，铈阳离子丰富的配位几何结构有助于通过调节阴离子FBBs来调整相关化合物的结构。
