- The formation of these compounds occurs in a surprisingly facile way by reactions of LnI 2 (Ln = Yb, Eu, Sm) either with a 1,4-oligosilanyl dianion [K-Si(SiMe 3 ) 2 SiMe 2 SiMe 2 Si(SiMe 3 ) 2 -K] ( 1 ) or with (Me 3 Si) 3 SiK ( 3 ) to give either the corresponding neutral metallacyclopentasilanes ({Me 2 Si(Me 3 Si) 2 Si} 2 )Ln·(THF) 4 (Ln = Yb ( 2a ), Eu ( 2b ), Sm ( 2c )) or the neutral disilylated complexes ({Me 3 Si} 3 Si) 2 Ln·(THF) 3 (Ln = Yb ( 4a ), Eu ( 4b ), Sm ( 4c )).
