Figure 5
Isosurface of the electron density difference at 0.03 e Å⁻¹. Sn atoms, oxygen atoms and lead atoms are represented by violet, red and gray spheres, respectively. The yellow circle highlights a channel running parallel to [001], which hosts the 6s² stereochemically active lone electron pairs of the Pb²⁺ ions, which appear as umbrella shaped surfaces.
