From BaAl2(BO3)2O to SnAl2(BO3)2F2: structure transformation based on ion regulation

Abstract

Using BaAl2(BO3)2O as a structural template to explore the Sn–Al–B–O–F system, a new tin(II)-containing aluminum borate fluoride compound, SnAl2(BO3)2F2, was synthesized successfully using the high-temperature solution method in a closed system. It possesses AlBO6F2 units which are interconnected further to form Al–B–O–F channels, and the Sn atoms reside in the related channels. To the best of our knowledge, SnAl2(BO3)2F2 is the first case with isolated BO3 groups in tin(II) borates. The UV-vis-NIR diffuse reflectance spectrum indicates that its ultraviolet (UV) cutoff edge is about 240 nm. Furthermore, the first-principles calculations of SnAl2(BO3)2F2 were carried out.
