[RbSrX][(BS)] (X = Cl, Br): two salt-inclusion thioborates with large birefringence and structure transformation from centrosymmetric to asymmetric
[RbSr 3 X][(BS 3 ) 2 ] (X = Cl, Br), two salt-inclusion chalcogenides with planar [BS 3 ] as anionic units, were obtained. Structure analysis indicates that the size effect of halogens may adjust the arrangement between the [BS 3 ] units and further lead to the CS-to-NCS structure transformation. Ex...

). This work indicates that the thioborate family is a rich source to explore structure chemistry and promising infrared functional materials.
