Description

The charge densities in ReO3 were investigated by the x-ray structural analysis. The anisotropic charge distributions were found around a Re atom, which is attributable to the π bond formed by Re 5d (tsub(2g) and O 2p electrons. The calculated difference electron density map by the DV-Xα cluster method supports qualitatively the present observation. The measured thermal vibrations of oxygen atoms were highly anisotropic. The M-mode oxygen displacements will be readily enhanced by the existence of high pressures. (author)
