Hydroxamate binding modes and protonation states have yet to be conclusively determined. Molecular titanium( IV ) phenylhydroxamate complexes were synthesized as structural and spectroscopic models, and compared to functionalized TiO 2 nanoparticles. In a combined experimental–theoretical study, we find that the predominant binding form is monodeprotonated, with evidence for the chelate mode.
