The crystal structures and their changing trend in the strontium–bismuth-oxide system are critical for the studies of the related systems and their applications. The crystal structure of Sr3Bi2O6 was obtained for the first time in the space group of R![[3 with combining macron]](https://www.rsc.org/images/entities/char_0033_0304.gif)
with a huge unit cell of a = b = 25.1146(19) Å and c = 18.3685(16) Å and all bismuth ions are Bi3+ forming [BiO3] trigonal pyramids. Sr3Bi2O6 is a key compound for the structural change trend in the SrO–Bi2O3 binary oxide system at 1000 °C. With a decrease in the bismuth content, its valence state changes from +3 to +5 and Bi–O polyhedra changes from connected to isolated before Bi(V) appearance. In the system, the boundary of the solid solution β-phase (Sr1−xBixO1+0.5x) at 900 °C was also determined accurately as 0.770 ≤ x ≤ 0.862, experimentally.

锶-铋-氧化物体系的晶体结构及其变化趋势对相关体系及其应用的研究至关重要。Sr的晶体结构3的Bi 2 ö 6得到的空间群的在第一时间- [R具有一个巨大的单元电池一个= b = 25.1146（19）a和C ^ = 18.3685（16）a和所有铋离子是Bi 3+形成[BiO 3 ]三角锥。Sr 3 Bi 2 O 6是SrO–Bi 2 O 3中结构变化趋势的关键化合物1000°C下的二元氧化物系统。随着铋含量的降低，其化合价态从+3变为+ 5，Bi-O多面体在Bi（V）出现之前从连接状态变为孤立状态。在该系统中，所述固体溶液β相的（Sr的边界1- X的Bi X Ò 1 + 0.5 X）在900℃下也准确地确定为0.770≤ X ≤0.862，实验。
