In a reaction of Cp2TiCl2 with PhSCH2CH2OH in the presence of NEt3, the complex Cp2TiCl(OCH2CH2SPh) (5) was obtained. These complexes were characterized by the 1H and 13C NMR, and the chemical shifts of the Cp rings for complexes 1-4 are nearly identical, despite differences in ligands for an indication of similar structures of these complexes around the metal center. Complex 4 crystallizes into the monoclinic P21/c space group with a = 13.806(3) ? B = 16.394(3) ? C = 7.838(2) ? B = 100.85(3)? Z = 4, R = 0.029, Rw = 0.044, and Gof = 1.19. The molecular structure of complex 4 shows that the 2-(phenylthio)ethoxide bonds to the Zr metal center through the alkoxide donor leaving the thioether donor free from coordination.
