Dynamic jahn teller distortion
WebJan 1, 2000 · The dynamic Jahn–Teller distortion present in the Cu([9]aneN 3) 2 2+ cation is removed upon replacement of one nitrogen donor with oxygen. The pseudo-octahedral structures of 2 and 3 , determined crystallographically, exhibit a strong tetragonal distortion with the two oxygen atoms in the elongated axial positions. WebJan 20, 2024 · This is shown to arise from the presence of a dynamic Jahn-Teller distortion that is stabilized by large vibrational anharmonicity. Our calculations further demonstrate that the dynamic Jahn-Teller-distorted structure of T d symmetry is lower in energy than the static Jahn-Teller distorted tetragonal D 2 d vacancy defect, in …
