Spectroscopic and kinetic data for the article "A Hafnium-Substituted Lindqvist Polyoxotungstate: Synthesis, Characterization, and Catalysis of H2O2-Based Oxidations"

This dataset contains the raw and processed IR, multinuclear NMR (17O, 183W), HR ESI-MS, PXRD, and kinetic data that underpin the manuscript: “Hafnium-substituted polyoxotungstate of Lindqvist structure: synthesis and catalytic properties in selective oxidations with aqueous H₂O₂.” Data include spectra for (nBu₄N)₆[{HfW₅O₁₈(μ-OH)}₂] and the zirconium analogue, MPS oxidation time-courses, H₂O₂ dismutation kinetics (including Arrhenius data), and singlet-oxygen probe reactions (tetramethylethylene, α-terpinene). Associated article: Inorganic Chemistry (submitted, 2025). DOI (to be added upon acceptance). Crystallography: CIF deposited at CCDC (2497611).
