A series of modified metallocene dichloride compounds,[SiRz (C5H4) z] MC12 (M= Ti, R= CH3; M= Zr, R= CH3, C2H5, n-C3H7), have been prepared to evaluate the presence of a dialkylsilyl bridge on their electrochemical behavior. The compounds have been characterized by elemental analysis and'H and') C NMR, and the molecular structures of [Si (CH3) Z (C5H4) z! MC1z, M= Ti, Zr, have been determined by X-ray diffraction methods. ...
