Synthesis and physico-chemical studies on the coordinating behaviour of chlorosulphate ion in metal tris(chlorosulphates), M(SO3Cl)3 [M = Cr, Mn, Fe], and their complexes

Article abstract of DOI:10.1080/00945719608004771

The solvolytic reaction of chromium(III) chloride, manganese(III) acetate and iron(III) chloride in chlrosulphuric acid afforded the formation of Cr(SO₃Cl)₃, Mn(SO₃Cl)₃ and Fe(SO₃Cl)₃ respectively, where chlorosulphuric acid acts both as medium of reaction as well as chlorosulphonating agent. These compounds are hygroscopic and dissolve in most non-polar solvents. The IR spectra of these compounds suggest that the SO₃Cl^- group is covalently bonded to the metal ion as evidenced by a shift of v₁(A) to higher frequency and splitting of doubly degenerate (E) modes. The observed values of magnetic moments and the band positions in the electronic spectra of these compounds are consistent with the octahedral geometry such that the SO₃Cl^- group is coordinated in a bidentate manner to the metal ions.
