Co-ordination chemistry of octamethyl-5,5′-di(2-pyridyl)ferrocene†

摘要: The platinum complex [{PtCl2(C2H4)}2(dpf*) 1 [dpf* = octamethyl-5,5′-di(2-pyridyl)ferrocene] has been obtained by the reaction of dpf* with K[PtCl3(C2H4)]. [Cu(NCCH3)4]+[BF4]– afforded copper complexes [Cu(dpf*)]+ [BF4]–2 and [Cu(dpf*)]+[CuCl2]–3 as well ferrocenium salt [dpf*]+[BF4]–4, depending on stoichiometry. crystal structures 1–4 have determined X-ray diffraction. acts a bridging ligand in case trans-chelating 2 3, which contain near-linear two-co-ordinate centres. Complex 3 shows remarkably short, ligand-unsupported CuI· · ·CuI contact [281.0(2) pm]. A cyclovoltammetric study revealed an unprecedentedly high anodic shift half-wave potential ferrocene moiety upon co-ordination Cu+ dpf*.
