Reconnected InChI-to-IUPAC Dataset for Metal-Containing Compounds

This dataset contains paired standard InChI, reconnected InChI, and IUPAC systematic names for metal-containing compounds to support InChI-to-IUPAC translation research. Records include category labels and metal annotations (category, has_metal, primary_metal) and derived length fields (standard_inchi_len, reconnected_inchi_len, iupac_len). The dataset was cleaned by removing invalid/placeholder names, enforcing InChI format checks, applying length constraints, normalizing whitespace, and deduplicating records based on unique structure–name pairs.
