Spectrophotometric Study of Iron‐bis(2‐hydroxymethyl‐5‐hydroxy‐4‐pyrone‐6)‐ketone Complexes

Abstract

The interaction between iron(III) and bis(2‐hydroxymethyl‐5‐hydroxy‐4‐pyrone‐6)‐ketone has been investigated by spectrophotometric methods. Continuous variation and mole ratio curves show evidence that 2:3 and 1:2 complexes are formed. The first step of the reaction involves the formation of an 1:1 complex.
