This preprint describes POM-DB, a computation-ready experimental polyoxometalate structural dataset. The associated dataset is deposited on Zenodo under DOI 10.5281/zenodo.20370381. It contains 1936 curated POM-level records, 6329 associated material records, released CML structure files for all POM-level records, JSON schema files, validation code, topology-analysis code, and documentation. The preprint presents the motivation, curation workflow, record model, data fields, validation checks, and usage notes for the dataset. The resource is intended for structure inspection, format conversion, descriptor generation, structural classification, cheminformatics, and data-driven reuse in polyoxometalate chemistry.
