Synthesis and characterization of the neutral lanthanide silyl complexes (.eta.5-C5Me5)2LnSiH(SiMe3)2 (Ln = Nd, Sm)

Synthesis and reactivity of bis(heptamethylindenyl) yttrium (Ind*2Y) complexes containing alkyl and hydride ligands: crystal structure of Ind*2YCl(THF)

“…After 6.5 h, 3.6 equiv of PhSiH 3 were consumed and 0.64 equiv of (PhSiH 2 ) 2 had formed (relative to a Cp 2 Fe internal standard). For comparison, PhMeSiH 2 was also observed as a product in the reaction of Cp* 2 YMe(THF) with PhSiH 3 [26][27][28]. The reactions of both complex 3 and Cp* 2 YMe(THF) with PhSiH 3 were very rapid at room temperature, indicating that the increased steric bulk of the Ind* ligand (vs. Cp*) does not significantly affect reactivity with small substrates such as PhSiH 3 .…”

Group 4 Metal and Lanthanide Complexes in the Oxidation State +3 with Tris(trimethylsilyl)silyl Ligands

“…31 Earlier, Radu and Tilley prepared similar compounds by σ-bond metathesis reactions of Cp* 2 LnCH(SiMe 3 ) 2 with SiH 2 (SiMe 3 ) 2 to obtain Cp* 2 LnSiH(SiMe 3 ) 2 (Ln = Sm, Nd). 36−38 Our own attempts in this field were mostly concentrating on reactions of oligosilanides with iodides of Sm(II), Yb(II), and Eu(II). 33−35 However, we also reported a study on the synthesis of metallacyclosilanes with lanthanidocenes, which were formed as ate-complexes reactions of α,ω-oligosilanyl dianions with lanthanidocenes Cp 3 Ln.…”

Open-Shell Lanthanide(II+) or -(III+) Complexes Bearing σ-Silyl and Silylene Ligands: Synthesis, Structure, and Bonding Analysis

“… 11 In the latter complex, the K ion coordinates to two Cp* ligands of different molecules, one THF moiety, and even to the SiH 3 ligand, forming a two-dimensional-layered structure in the solid state. 12 The Cp*K unit thus serves as a neutral stabilization ligand for Ln II complexes otherwise intractable and difficult to isolate.…”
