Abstract
A novel and unusual three-dimensional network of tin atoms is present in NaSn5, in which metallic layers analogous to those in β-Sn alternate with tetravalent units analogous to α-Sn. The compound shows the emergence of pentagonal-dodecahedral units from the metallic β-Sn modification (see structure on the right; all unlabeled spheres are Sn atoms). Quantum-mechanical investigations indicate the simultaneous presence of structural regions with localized and delocalized bonds.
