Extended Data Fig. 1: Comparison of different metrics for the quantification of octahedral distortion.
From: Homomeric chains of intermolecular bonds scaffold octahedral germanium perovskites
A plot of Baur distortion index vs a, Bond angle variance b, Quadratic elongation c, Effective coordination number d, Bond distortion \((\triangle d)\) e, Polyhedral volume f, Average bong length. Octahedral perovskites are identified by the yellow circles in each graph. See Supplementary note 4 for the definition of each metric.
