Abstract

Na₂B₁₀H₁₀ exhibits exceptional superionic conductivity above ca. 360 K (e.g., ca. 0.01 S cm^-1 at 383 K) concomitant with its transition from an ordered monoclinic structure to a face-centeredcubic arrangement of orientationally disordered B₁₀H₁₀^2- anions harboring a vacancy-rich Na⁺ cation sublattice. This discovery represents a major advancement for solid-state Na⁺ fast-ion conduction at technologically relevant device temperatures. (Graph Presented).
