Indenyl-derived ytterbocene(II) complexes [1-(SiHR2)-2-R′-C9H5]2Yb(L)2 (R = Me, C6H5; R′ = H, Me; L = donor ligand) have been synthesized via silylamine elimination from Yb[N(SiMe3)2]2(THF)2 and the indene derivatives in hexane at ambient temperature. The `SiH-decorated' silyl substituents assist in the examination of the fluxional behavior of the stereoisomers in solution, the ratio and interconversion of which are affected by the size and ring position of the substituents as well as the type of donor ligand, e.g., THF vs TMEDA.
