The 4d–4f heteronuclear title complex, [AgCe(C14H8N2O5)2(H2O)]n, has a three-dimensional framework structure, generated by the carboxylate and pyridyl groups of the 5-(isonicotinamido)isophthalate (INAIP) ligands bridging the metal ions. The CeIII atom is coordinated by eight O atoms from six INAIP ligands and a water molecule in a distorted tricapped trigonal–prismatic geometry, while the AgI atom has a distorted trigonal–planar AgN2O geometry. O—H⋯O and N—H⋯O hydrogen bonds and π–π interactions between the pyridine and benzene rings [centroid–centroid distances = 3.642 (4) and 3.624 (3) Å] stabilize the crystal structure.
