Abstract
A new grey colour polymorph of CsSnBr3 with non-cubic phase at 295(±1) K is observed. Contrary to black and yellow polymorphs, it seems that not only the β-α transition at 292 K shifted to 304 K but also the new β
3-phase with second-order phase transition (β
2-β
3) can be seen in this new grey polymorph. The structural refinement shows the monoclinic
phase with holohedry for β
3-CsSnBr3 against the group-subgroup theory. However, the parameters
and
are suggesting pseudo-tetragonality for β
3-CsSnBr3.
