Two antimony selenites, SbOSeO and SbO(SeO), were synthesized by simultaneously incorporating stereochemically active lone pair electrons containing SeO and Sb. These compounds are structured with [SbO] polyhedra and [SeO] units within a two-dimensional framework. Both of them exhibit cutoffs at 300 and 330 nm within the ultraviolet (UV) range and demonstrate significant birefringence, with indices of 0.069 and 0.126 at 546 nm, respectively. These properties highlight their potential as UV birefringent materials. Structural analyses and theoretical calculations reveal that their exceptional birefringence results from the synergistic interactions between SeO anions and Sb cations.
通过同时引入含有孤对电子的立体化学活性的 SeO 和 Sb，合成了两种亚硒酸锑，即 SbOSeO 和 SbO(SeO)。这些化合物在二维框架内由 [SbO] 多面体和 [SeO] 单元构成结构。它们在紫外（UV）范围内均在 300 和 330 nm 处出现截止，并表现出显著的双折射，在 546 nm 处的双折射指数分别为 0.069 和 0.126。这些特性突出了它们作为紫外双折射材料的潜力。结构分析和理论计算表明，它们优异的双折射源于 SeO 阴离子和 Sb 阳离子之间的协同相互作用。
