Chromium Jahn-Teller effect

In the structure, the copper (or chromium) atom has a greatly distorted octahedral coordination, with two bond distances much longer than the other four (difference = 0.38 A for Cu, 0.36 A for Cr) and small, but significant differences between the pairs of short distances. The major distortion is correlated with the d9, or high-spin d4, electronic configuration of Cu(II) and Cr(II), respectively, giving an uneven occupation of the eg orbitals—the Jahn-Teller effect. The differ-... [Pg.86]

Chromium in its dichloride has a ct electronic configuration and in its crystals is subject to the Jahn-Teller effect. Indeed, chromium has a tetragonally distorted octahedral coordination in its crystals [89], CrCl2 is a fascinating molecule in that it displays both the Jahn-Teller and the Renner-Teller effects. [Pg.307]

Abstract A brief review of my work with Carl Ballhausen in 1967-1968 and subsequent work. The assignments of the vibronic sidebands in the emission spectra of chromium ammine complexes are given with some comments on the Jahn-Teller effect in the emissive state. Energy transfer and cross relaxation phenomena are discussed and the shell model for this processes in lanthanide elpasolites is presented... [Pg.30]
