Organometallic compounds actinide

Compounds of the stoichiometry MCp 2X2 provide an opportunity to compare actinides with block elements. Several such species have been studied both by gas phase PE experiments as well as by theoretical approaches. Thus, the first comparative study of the PE spectra of a series of transition metal and actinide organometallic compounds with exacdy the same ligand array was carried out on MCp 2X2 (M = Zr, Th, U, and X = CH3 and Cl) complexes. Comparable bonding was found along the series with smaller differences than encountered in the parent series involving transition elements. The major differences between Zr and the actinides are due to the involvement of yin the bonding. 

In the second part, a more explicit discussion of the photochemical reaction of some interesting actinide organometallic compounds will be presented.

The first weU-characterized organometallic compounds of the lanthanides or actinides were the tricyclopentadienides of various lanthanide ions S3mthesized by Birmingham and Wilkinson in 1954 (97—98). Anhydrous metal chlorides were reacted with sodium cyclopentadienide in tetrahydrofuran as follows ...

Among the natural and artificial radioactive elements (Tc, Pm, Po, Fr, Ra, Ac, and actinides), coordination and organometallic compounds of only technetium and the actinide series (An) are well represented at the present time. The interest in their metal complexes has been motivated by the extended use of Tc, available in kilogram amounts, for medical and technical purposes, meanwhile actinides are important on their own for the nuclear industry. A lot of original papers, reviews, and chapters of some books are dedicated to Tc and An complexes [263-281], In the present section, dedicated to the coordination and organometallic chemistry of the actinides and Tc, we intend to present the synthetic techniques for these compounds according to their ligand nature. 

Actinide organometallic complexes are compounds containing an actinide-carbon 7i-bond, an actinide-carbon a-bond, or a combination of both. Actinide organometallic complexes are known for all of the early actinide elements (An)...
