Abstract: The title heteronuclear complex, {[AgHo(C₁₄H₈N₂O₅)₂(H₂O)]·2H₂O}_n, has a three-dimensional polymeric structure, generated by the carboxylate and pyridine groups of the 5-(isonicotinamido)isophthalate (INAIP) ligands bridging the metal atoms. The Ho^III atom is coordinated by seven O atoms from INAIP ligands and a water molecule in a distorted square-antiprismatic geometry, while the Ag^I atom has a distorted trigonal-planar AgN₂O geometry. Intermolecular O-HO and N-HO hydrogen bonds stabilize the crystal structure.
