Herein, a new congruently melting mixed-anion compound Cs4B4O3F10 has been characterized as the first fluorooxoborate with [BF4] involving heteroanionic units. Compound Cs4B4O3F10 possesses two highlyfluorinated anionic clusters and therefore its formula can be expressed as Cs3(B3O3F6) ⋅ Cs(BF4). The influence of [BF4] units on micro-symmetry and structural evolution was discussed based on the parent
在此,一种新的同熔混合阴离子化合物 Cs 4 B 4 O 3 F 10已被表征为第一个具有 [BF 4 ] 的含杂阴离子单元的氟代硼酸盐。化合物Cs 4 B 4 O 3 F 10具有两个高度氟化的阴离子簇,因此其分子式可以表示为Cs 3 (B 3 O 3 F 6 ) ⋅ Cs(BF 4 )。基于母体化合物讨论了[BF 4 ]单元对微对称性和结构演化的影响。更重要的是,Cs 4B 4 O 3 F 10在所有可用的硼酸盐中显示出最低的熔点,从而为此类系统创造了新的记录。这项工作对于使用全氟化 [BF 4 ] 单元丰富和定制硼酸盐的结构具有重要意义。

[SbF6]– and [BiF6]– has been confirmed by Raman spectroscopy. The low‐ and high‐temperature phases of Bi/Sb mixed‐anion compounds are isotypic with the corresponding A[XeF5][SbF6]2 (A = Rb, Cs) phases. No reactions were observed in the AAsF6 (A = Rb, Cs)/[XeF5][AsF6], ASbF6 (A = K, [H3O]+)/[XeF5][SbF6], and KBF4/[XeF5][SbF6] systems. In the CsBF4/[XeF5][SbF6] system, a metatheticalreaction occurred
