Darstellung Fluorhaltiger Hexahalogenorhenate(IV)

Preparation of Fluorine Containing Hexahalorhenates(IV) By oxidative ligand exchange on hexahalorhenates(IV) with BrF₃, KBrF₄, IF₅ and Br₂ or by substitution reactions in organic solvents as well as by solid state exchange processes 20 fluorine containing mixed ligand complexes are prepared for the first time: cis-ReFBrI₄]^2?, fac-ReFBr₂I₃]^2?, mer-ReFBr₃I₂]^2?, trans-ReFBr₄I]^2?, ReFBr₅]^2?, trans-ReFCl₄I]^2?, trans-ReFCl₄Br]^2?, ReFCl₅]^2?, cis-ReF₂I₄]^2?, fac-ReF₂BrI₃]^2?, all-cis-ReF₂Br₂I₂]^2?, cis-ReF₂BrI₂]^2?, mer-ReF₂Br₃I]^2?, cis-ReF₂Br₄]^2?, cis-ReF₂Cl₄]^2?, fac-ReF₃I₃]^2?, fac-ReF₃BrI₂]^2?, fac-ReF₃Br₂I]^2?, fac-ReF₃Br₃]^2? and fac-ReF₃Cl₃]^2?. The isolation of the pure complexes has been achieved by ion exchange chromatography on DEAE-cellulose. They are characterized by stereospecific exchange reactions in solution and by elementary analyses.
