Fq. Song et al., SYNTHESIS AND STRUCTURAL STUDIES OF TETRAMETHYLDISILOXANYL DICYCLOPENTADIENYL LANTHANIDE CHLORIDES, Gaodeng xuexiao huaxue xuebao, 19(9), 1998, pp. 1436-1439
There reactions of anhydrous NdCl3 and/or SmCl3 with Na-2(C5H4SiMe2)(2
)O in 1 : 1 molar ratio in THF afforded the title compounds [O(Me3SiC5
H4)(2)Ln (mu-Cl) (THF)](2)[Ln = Nd (1), Sm(2)], Compounds 1 and: 2 wer
e characterized by elemental analysis. X-ray structural analysis revea
led that 1 and 2 are dimeric compounds bridged by two chloro atoms.
