Molecular Ln(III)−H−E(II) Linkages (Ln=Y, Lu; E=Ge, Sn, Pb)

Following the alkane‐elimination route, the reaction between tetravalent aryl tintrihydride Ar*SnH 3 and trivalent rare‐earth‐metallocene alkyls [Cp* 2 Ln(CH{SiMe 3 } 2 )] gave complexes [Cp* 2 Ln(μ‐H) 2 SnAr*] implementing a low‐valent tin hydride (Ln=Y, Lu; Ar*=2,6‐Trip 2 C 6 H 3 , Trip=2,4,6‐triisopropylphenyl). The homologous complexes of germanium and lead, [Cp* 2 Ln(μ‐H) 2 EAr*] (E = Ge, Pb), were accessed via addition of low‐valent [(Ar*EH) 2 ] to the rare‐earth‐metal hydrides [(Cp* 2 LnH) 2 ]. The lead compounds [Cp* 2 Ln(μ‐H) 2 PbAr*] exhibit H/D exchange in reactions with deuterated solvents or dihydrogen.
