Comparison of anion and cation dynamics in a carbon-substituted closo-hydroborate salt: ¹H and ²³Na NMR studies of solid-solution Na₂(CB₉H₁₀)(CB₁₁H₁₂).

ABSTRACT: The hexagonal mixed-anion solid solution Na₂(CB₉H₁₀)(CB₁₁H₁₂) shows the highest room-temperature ionic conductivity among all known Na-ion conductors. To study the dynamical properties of this compound, we have measured the ¹H and ²³Na nuclear magnetic resonance (NMR) spectra and spin-lattice relaxation rates in Na₂(CB₉H₁₀)(CB₁₁H₁₂) over the temperature range of 80-435 K. It is found that the diffusive motion of Na⁺ ions can be described in terms of two jump processes: the fast localized motion within the pairs of tetrahedral interstitial sites of the hexagonal close-packed lattice formed by large anions and the slower jump process via octahedral si
