Abstract

The complex CpYCl2(THF)3 (Cp C5H5) was obtained by reacting YCl3 with sodium and cyclopentadiene (1:1:5 molar ratio) in THF at room temperature, which has been studied by X-ray crystallography. The complex is monomeric with the ytrium atom coordinated by one Cp ring centroid, three oxygen atoms from three THF molcecules and two chloride atoms to give rise to a distorted octahedral coordination. The YC(Cp) bond lengths range from 2.59(3) to 2.73(4) Å and average 2.65(3) Å. The THF molecules coordinate to the yttrium atom with YO distances of 2.34(2), 2.35(2), 2.35(2) and 2.50(2) Å, respectively. The YCl bond lengths are 2.630(8) and 2.625(7) Å, respectively. Some significant parameters of the title complex have been compared with the corresponding values of the known isostructural organolanthanide complexes of Nd, Gd, Ho, Er and Yb.
