Reply to the 'Comment on "Investigation of Zr(IV) and 89 Zr(IV) complexation with hydroxamates: progress towards designing a better chelator than desferrioxamine B for immuno-PET imaging"' by A. Bianchi and M. Savastano, Chem. Commun., 2020, 56, D0CC01189D

Abstract : The alternative analysis of A. Bianchi and M. Savastano is a valuable contribution to the understanding of the complex systems at stake in the complexation chemistry of Zr4+ by considering polynuclear species. Placed in the context of nuclear medicine where such aggregates are unlikely and considering recent literature data, this however points out that no clear agreement exists to describe such complex formation.
