Abstract: The crystal and molecular structure of titanium ether complex has been determined by X-ray diffraction. TiCl_4 and Et_2O can form 1:2 complex, TiCl_4·2Et_2O, which is in cis-configuration. The crystal belongs to monoclinic space group C_(2h)~5P21/n with unit cell parameters: a=0.8877(4) nm, b=1.3115(8) nm, c=1.3437(8) nm, β=98.27(5)°, Z=4. The structure was refined to R_1=0.108、R_2=0.127 for 1002 reflections.
It has been showed that the titanium ether complex which has been used to modify the catalyst (3TICl_3·AlCl_3) is TiCl_4·2Et_2O. The powder pattern and infrared spectra of the complex have also been got. Some bases for characterizing the catalyst have provided.
