Crystal structure of dicarbonyl(π-cyclopentadienyl)(pentafluoro-phenylsulphonyl-S)iron

Abstract

The product of the reaction between C₆F₅SO₂Cl and the anion [(π-C₅H₅)Fe(CO)₂]^– is the air-stable compound C₆F₅SO₂Fe(CO)₂(π-C₅H₅). This orange complex crystallizes in the monoclinic system, space group P2₁/c, a= 10·97(2), b= 12·12(2), c= 12·06(2)Å, β= 117·6(2)°, Z= 4. The crystal structure analysis based on 754 non-zero independent reflections has resulted in a final R 10·7% and shows the compound to be an S-sulphinato-complex.
