Charge sum 0 (balanced)
Tolerance factor t 0.884
Octahedral factor ΞΌ 0.367
Estimated a (BβX contact / AβX contact) 5.36 / 4.74 Γ
t: Below 0.9: octahedral tilting is expected (distorted, e.g. orthorhombic), if the perovskite forms at all.
ΞΌ: Below 0.414: B is small for an octahedral hole β octahedral coordination is geometrically strained.
Lattice parameter a used for the model
BβX contact AβX contact Custom a = 5.360 Γ
Β· Ο β 3.09 g/cmΒ³
An ionic-radius estimate, not a relaxed value. If t β 1 the two contact estimates disagree β that mismatch is why real structures tilt or distort.
