77 random COD entries from the COD OPTIMADE index, 39 with carbon in the formula and 38 without. For each CIF: whether it carries a PubChem pointer (_cod_related_entry_database PubChem), the CID it names, and that CID's PubChem formula and title. Each entry came from a single random offset, so there is no series clustering. Companion to the post on the MgO/TiO2/Fe2O3 gap.
