Webt -- Goldschmidt tolerance factor. In an ideal cubic perovskite crystalline structure the A-site and B-site cations optimize their equilibrium bond distances to the oxygen elements without inducing any distortion of the unit cell at t = 1. When 0.78 < t < 1.05, a distorted perovskite structure can normally be stabilized.
