Synthesis, Characterisation, Complexation and Electrochemistry of Linear Tridentate FcE(CH2)3E′(CH2)3EFc (E, E′ = Se or Te) Ligands: X-ray Crystal Structures of FcSe(CH2)3Se(CH2)3SeFc and [PtCl{FcSe(CH2)3Se(CH2)3SeFc}]PF6 {Fc = [Fe(η5-C5H5)(η5-C5H4)]}

A series of Linear tridentate ligands, FcE(CH2)(3)E'(CH2)(3)EFc (E, E' = Se or Te), was synthesised. Their chloropalladium(II) and chloroplatinum(II) complexes were also prepared. The new compounds were characterised by a range of spectroscopic and analytical techniques, including multinuclear NMR spectrometry and X-ray crystallography. In an electro-chemistry study of the complexes no communication between the ferrocenyl centres was observed, regardless of the through-bond Fe center dot center dot center dot Fe distance.
