Na2.8Cu5Sn5.6: A Crystalline Alloy Featuring Intermetalloid ${{}_infty ^{bf{1}} left{ {{bf{Sn}}_{{bf{0}}{bf{.6}}} {bf{@Cu}}_{bf{5}} {bf{@Sn}}_{bf{5}} } right}}$ Double-Walled Nanorods with Pseudo-Five-Fold Symmetry

Not quasi‐crystalline: Approximate five‐fold symmetry appears in bronze‐type Cu–Sn rods that are separated by Na atoms in Na2.8Cu5Sn5.6 (see picture). The rods are compared to the [Sn@Cu12@Sn20]12− cluster in the recently characterized A12Cu12Sn21 phases (A=Na–Cs), and a saltlike description in anal...
