The preparation and characterization of the three ferrocene based dithiolane complexes [(η5-C5H5) Fe(η5-C5H4)NHC(O)(CH2)4CHS 2CH2CH2]1, [(η5- C5H5)Fe(η5-C5H 4)CH2OC(O)(CH2)4CHS2CH 2CH2] 2 and [(η5-C5H 5)Fe(η5-C5H4)NHC(O)(CH 2)CHS2CH2CH2] 3, with different spacer groups between the ferrocenyl moiety and the dithiolane unit, are reported. The complexation of 1 and 2, using the oxidative addition of the S-S bonds to Pt(0), is also described, leading to the square planar Pt(II) complexes [Pt(PPh3)2(S2CH2CH 2CH-κ2-S,S)(CH2)4C(O) NH(η5-C5H4)Fe(η5-C 5H5)] 4 and [Pt(PPh3)2(S 2CH2CH2CH-κ2-S,S)(CH 2)4C(O)OCH2(η5-C 5H4)Fe(η5-C5H5)] 5, respectively. The reduction of the S-S bond in 1 and 2 yields the corresponding dithiols; these can be deprotonated and treated with ClSiMe3 to prepare [(η5-C5H5)Fe(η5- C5H4)NHC(O)(CH2)4CH(SSiMe 3)CH2CH2(SSiMe3)] 7 and [(η5-C5H5)Fe(η5-C 5H4)CH2OC(O)(CH2) 4CH(SSiMe3)CH2CH2(SSiMe 3)] 9, respectively. The complexes were characterized via NMR and UV-Vis absorption spectroscopy, cyclic voltammetry and single crystal X-ray diffraction for 1 and 4.
