Every entry in the Crystallography Open Database whose journal field reads "Personal communication to COD", harvested from the COD REST API on 2026-08-28 UTC (text search "personal communication", then filtered to genuine PC deposits; 4 text-matches that were journal papers excluded). 194 rows, 2011-2026. Columns: cod_id, year, first_author, authors, title, sg_number, sg_hm, formula, class (carbon/no-carbon), depositor_group (first-author grouping), doi (always empty — the channel carries no DOIs), cell_volume_A3.
