Other compounds with this structure

  • CsNO3 (II) and TlNO3 (III)

  • RbNO3 takes on four distinct phases with increasing temperature (Shamsuzzoha, 1988). Phase IV, presented here, is the ground state, stable up to 437 K. Phase III, stable in the range 437–492 K, is in the cesium chloride ($B2)$ structure, with rubidium atoms on the cesium sites and orientationally disordered NO3 ions on the chlorine sites. Phase II, stable up to 564 K, is possibly a body–centered cubic structure with up to eight formula units in the conventional unit cell. Phase I, stable up to the melting point, is thought to be a sodium chloride ($B1$) structure, with NO3 again playing the role of chlorine.
  • The Phase IV structure also exists in the enantiomorphic space group $P3_{2}$ #145. (Shamsuzzoha, 1982)
  • We used the data taken at room temperature, 298 K.
