Reaction of yttrium trichloride with indenyl sodium in 1: 2 molar ratio in THF at 50 ° C led to disproportionation of the ionic complex [(C9H7) 3Yb] 2Cl [Na.6THF] (I). The X-ray structure analysis showed that the complex I was an ion pair consisting of the anion {[(C9H7) 3Yb] 2Cl} - and the cation [Na.6THF] + and the anion was prepared by the reaction of two (C9H7) 3Yb (C9H7) 3 Yb) 2 Cl] [Na · 6THF] is a triclinic system with space group P1, a = 1.0682 (2) nm and b = 1 2 687 (3) nm, c = 1 2 869 (2) nm, α = 87 2 2 3 (1) °, β = 81 75 5 °, γ = 88 2 17 °, V = , Z = 1. The structure of complex I was determined by heavy atom method and corrected by full matrixleast squares method. The coincidence factors were R = 0 0 62 and Rw = 0 0 72. The complex {[(C9H7) 3 Yb] 2 Cl} [Na · 6THF] reacts with sodium metal to form (C9H7) 2 Yb · 2THF (II). The molecular structure of complex II is X-rayed.
