Synthesis, characterization and cytotoxicity studies of methoxy alkyl substituted metallocenes

►The manuscript describes the synthesis and characterization of some complexes of titanium and one of zirconium bearing cyclopentadienyl-ethenyl-methoxyl ligands. ►The manuscript describes cytotoxic activities on MCF-7, HEK-293, J774.A1 cell lines of some complexes of titanium and one of zirconium, bearing cyclopentadienyl-ethenyl-methoxyl ligands. ►The cytotoxic activities of complexes of titanium and zirconium, bearing cyclopentadienyl-ethenyl-methoxyl ligands were related to rate of hydrolysis.
