What is Orientational disorder in cubic CsNO2 by neutron powder diffraction about?
Neutron powder diffraction data of cubic CsN0 2 at room temperature (space group Prriim, a = 4.389 Ä) are analyzed with several models for the orientationally disordered N0 2 group. The density distribution of Ο and Ν atoms are expanded on spherical shells with cubic harmonics. The density of the Ο atoms is concentrated close to the <100) axes. The shell radii refine to 0.40(2) and 1.19(2) A for Ν and O, respectively. Split-atom and Frenkel models constructed on this basis are consistent with the experimental data. There are two Frenkel models (superposition of rigid N0 2 groups) which can coexist in the crystal: in the first model the 0-0 direction of a molecule is parallel to <100) and in the second parallel to <110). The configurational entropy and the two distinct orientations are consistent with published thermodynamic and Raman data.
