Fig. 5: Variable-temperature SCXRD.

a Variation of unit cell characteristics (a, b, c, α, β, γ) and unit cell volume during the PT from AIIα to AIIβ, cyan and lime colors represent the two different phases AIIβ and AIIα, respectively. b Change in unit cell length and volume in BII. The data points correspond to the cooling of the crystal from RT to 100 K.
