Actinide complexes dioxo

Actinide complexes rarely follow the conventional rules, for example, 18-electron rule, typically found in inorganic and coordination chemistry of the transition metals. A prime example of the difference in actinide chemistry is the pervasiveness of the linear dioxo rmit, which is immatched in transition metal chemistry. For the actinides, the trans dioxo structure is maintained through different metal ions, oxidation states, and valence electron cormts, for example,... 

A vibrational spectral study of compounds of actinide(v) dioxo cations showed that for anhydrous complexes, the v, tisym band at 785—815 cm" for Am=02 was a... 

It is frequently argued that a specific property of 5f g oup M(VI) nd M(V) is the formation of linear dioxo complexes, M022 and M02. Their most striking property is the coexistence of oxo and aquo ligands, which is exceedingly rare in the rest of the elements. There are characteristic differences found frequently between the oxo ions of the V- and VI-valent actinides, uranium through americium, and those of the d elements in the same valence states.
