Samarium complexes samarocene

The complex SmCpj was synthesized by metal vapour reaction of samarium with Cs(CH3)5H as a green product or by desolvation of the red SmCpj 2THF by sublimation. The crystal structure of the complex SmCpj shows it to be decamethyl samarocene with bent metallocene disposition [138], The Cg-Sm-Cg angle of 140.1° is greater than 136.7 in the desolvated analogue. The Sm-C bond distance is reduced, 2.79(1) A compared to 2.86 (3) A and the structure of SmCpj is shown in Fig. 6.12. [Pg.445]

The title complex was first prepared from the reaction between zerovalent samarium vapor and pentamethylcyclopentadiene at -120°C [37a]. Later it was found that Sml2(THF)2 was a more convenient entry to the samarocene(II) complex as treated with K(C5Me5). [Pg.69]
