A polarographic study of the iron-2-hydroxymethyl-6-(2′-hydroxymethyl-5′-hydroxy-4′-pyrone-6′)-pyranyl-3,2[ b]pyran-4,8-dione complex

A polarographic study has been carried out on the colored product formed in the interaction of iron(III) with 2-hydroxymethyl-6-(2′-hydroxymethyl-5′-hydroxy-4′-pyrone-6′)-pyranyl-3,2[ b]pyran-4,8-dione. Measurements using the differential pulse method show that iron(III) exhibits a coordination numb...

Description
Summary:A polarographic study has been carried out on the colored product formed in the interaction of iron(III) with 2-hydroxymethyl-6-(2′-hydroxymethyl-5′-hydroxy-4′-pyrone-6′)-pyranyl-3,2[ b]pyran-4,8-dione. Measurements using the differential pulse method show that iron(III) exhibits a coordination number of 2 and a reproducible formation constant that varies somewhat depending upon the supporting electrolyte employed.
