IUPACRed

IUPACRed is a collaborative online resource that applies IUPAC nomenclature principles to redox chemistry and related inorganic contexts. It aims to standardize the naming of redox-active inorganic and organometallic compounds and to serve as a reference for researchers, educators, and database curators. The project positions itself as a practical companion to the IUPAC Red Book by providing rules, examples, and links to primary literature.

Key features include a structure-to-name generator, a name-to-structure parser, and redox-state tagging that captures oxidation states, protonation, and ligand denticity. Names are aligned with current IUPAC conventions and traceable to Red Book sections. The platform offers an API and downloadable datasets for software integration and offline use.

Governance and scope: IUPACRed is overseen by a standing IUPAC committee on inorganic nomenclature with input from chemists worldwide. Its scope covers inorganic and organometallic species, including coordination complexes and clusters where redox states influence naming. The project publishes rules, example catalogues, and educational materials.

Development and impact: The project began as a pilot in 2022 and evolved into an openly editable database with moderation in 2023. It is free to access, with editing limited to verified contributors. Researchers cite IUPACRed as a reference for consistent naming in publications and databases.

Limitations and reception: As a developing resource, IUPACRed does not yet cover all redox species and may require contributors to resolve edge-case ambiguities. Ongoing updates and governance aim to address these gaps and align with evolving IUPAC standards.
