Poly[aqua­[μ(5)-5-(isonicotinamido)­isophthalato][μ(4)-5-(isonicotinamido)­isophthalato]cerium(III)silver(I)]

The 4d–4f heteronuclear title complex, [AgCe(C(14)H(8)N(2)O(5))(2)(H(2)O)](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 Ce(III) atom is coordinated by eight O atoms from six INAIP ligands and a water mol­ecule in a distorted tricapped trigonal–prismatic geometry, while the Ag(I) atom has a distorted trigonal–planar AgN(2)O 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.
