Two new cesium selenites containing TaO6 or TiO4F2 octahedra, namely, Cs(TaO2)3(SeO3)2 (1) and Cs(TiOF)3(SeO3)2 (2), have been prepared using standard high temperature solid-state method and hydrothermal reaction, respectively. Compound 1 crystallizes in P3̅m1 and features an unusual [(TaO2)3(SeO3)2]− sandwich-like double layer in which two [Ta(1)O3(SeO3)]3– layers are bridged by central Ta(2)O6 octahedra via corner-sharing, whereas Cs(TiOF)3(SeO3)2 with a polar space group P63mc features an interesting hexagonal tungsten oxide (HTO) layered topology and presents a strong second harmonic generation (SHG) of about 5 × KDP (KH2PO4), which is much larger than those of A(VO2)3(QO3)2 (A = K, Tl, Rb, Cs, or NH4; Q = Se, Te) with a similar HTO layered structure. Cs(TiOF)3(SeO3)2 is also type-I phase matching. The SHG of above-mentioned HTO materials can be enhanced greatly with the replacement of VO6 octahedra by TiO4F2 octahedra. Furthermore, thermal stabilities, UV–vis diffuse reflectance spectra, infrared spectra, relationship between crystal structure and SHG, and theoretical calculations were also reported.

铯(TAO 2)3(SEO 3)2和Cs(TIOF)3(SEO 3)2:结构和二次谐波变化引起由不同d 0 -TM协调八面体
使用标准品制备了两种新的含TaO 6或TiO 4 F 2八面体的硒化铯,分别为Cs(TaO 2)3(SeO 3)2(1)和Cs(TiOF)3(SeO 3)2(2)。高温固态法和水热反应。化合物1个结晶在P 3米1,并设有一个不寻常的[(TAO 2)3(SEO 3)2 ] -夹心状双层结构,其中两个[Ta(1)O 3(SeO 3)] 3–层通过中心Ta(2)O 6八面体通过角共享桥接,而Cs(TiOF)3(SeO 3)2极性空间群为P 6 3 mc的人具有有趣的六角形氧化钨(HTO)分层拓扑结构,并呈现出约5×KDP(KH 2 PO 4)的强二次谐波(SHG),比A的大得多。 (VO 2)3(QO 3)2(A = K,Tl,Rb,Cs或NH 4; Q = Se,Te)具有类似的HTO分层结构。CS(TIOF)3(SEO 3)2也I型相位匹配。通过用TiO 4 F 2八面体代替VO 6八面体,可以大大提高上述HTO材料的SHG 。此外,还报道了热稳定性,紫外可见漫反射光谱,红外光谱,晶体结构与SHG之间的关系以及理论计算。
