Structure and Properties of Perovskite Oxides | SpringerLink
In perovskite-type compounds, the value of t lies between approximately 0.80 and 1.10. It is noted that the oxides with the lower t values crystallize in the ilmenite structure, which is a polymorph of the perovskite structure. It seems superfluous to say that for the ideal cubic structure the value of t is close to 1 or at least greater than 0.89. . …
