Abstract

Upon cooling a single-phase sample of C₂₄Rb under N₂ pressure, intercalation of N₂ into C₂₄Rb starts immediately below RT. A single phase of C₂₄Rb(N₂)_x is formed, where N₂ resides at every Rb layer, and x increases monotonically as temperature decreases. In the temperature range 175 > T > 140 K a phase transition occurs, and for T ≤ 140 K three phases co-exist: C₂₄Rb, C₂₄Rb(N₂)_x and C₄₈Rb₂(N₂)_x. The third phase, has a stacking where N₂ resides at every second Rb layer, hence, it is second stage compound in the intercalation of N₂ in C₂₄Rb.

A single phase of C24Rb(N2)x is formed, where N2 resides at every Rb layer, and x increases monotonically as temperature decreases. In the temperature range 175 > T > 140 K a phase transition occurs, and for T ≤ 140 K three phases co-exist: C24Rb, C24Rb(N2)x and C48Rb2(N2)x.
