Computation-ready Experimental Polyoxometalate Structural Dataset

This dataset provides POM-DB, a computation-ready experimental polyoxometalate structural dataset. The release contains: 1936 curated POM-level records 6329 associated material records released CML structure files for all POM-level records a JSON schema, validation code, topology-analysis code, and documentation Each POM-level record links formula, composition, molecular mass, charge, classification labels, InChI/InChIKey identifiers, material records, CAS Registry Numbers, literature provenance, CML structure-file references, and graph-based topology annotations. The dataset is intended for structure inspection, format conversion, descriptor generation, structural classification, cheminformatics, and data-driven reuse.
