A homogeneous two-step reaction was observed when mixing Cr(III), present as hexaquo complex, with DTPA. The first reaction product, the electroactive 1:1 complex, turns into an electroinactive form in the second step. the results indicate that the second reaction product is presumably a 1:2 Cr(III)/DTPA complex.
