Synthesis, structure and electrochemistry of [Pt([10]aneS3)2][PF6]2([10]aneS3= 1,4,7-trithiacyclodecane)

Abstract

The orange complex [Pt([10]aneS₃)₂][PF₆]₂([10]aneS₃= 1,4,7-trithiacyclodecane) is centrosymmetric with primary S₄ co-ordination, Pt–S(5) 2.297(4), Pt-S(8) 2.309(4), Å, with long-range interactions to the two remaining S-donors, Pt ⋯ S(1) 3.233(4)Å; [Pt([10]aneS₃)₂]²⁺ shows a broad two-electron oxidation centred at E_½=+0.35 V (vs. ferrocene–ferrocenium) assigned to a Pt^II–Pt^IV couple.
