Abstract: | The title compound, also known as sodium nicotinate, Na+·C6H4NO2−, consists of two unique Na atoms coordinated to two unique pyridine‐3‐carboxylate ligands through the N atoms and carboxylate groups. One Na atom and one pyridine‐3‐carboxylate ligand lie on a twofold axis. Extensive Na coordination results in a three‐dimensional array comprising infinite NaO2CR chains linked by intrachain Na—N bonds. |
