Investigation of Zr(IV) and Zr-89(IV) complexation with hydroxamates: progress towards designing a better chelator than desferrioxamine B for immuno-PET imaging

[摘要]：Single crystal X-ray diffraction shows that Zr(IV) forms an octa-coordinated complex with 4 bidentate hydroxamates whose solution structures were investigated by utilizing density functional theory at the level of B3LYP/DGDZVP. Stability constants obtained by potentiometry were in accordance with the tendency observed when radiolabeling with Zr-89.
