Poly[[aqua[μ5-5-(isonicotinamido)isophthalato][μ4-5-(isonicotinamido)isophthalato]holmium(III)silver(I)] dihydrate]

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 HoIII atom is coordinated by seven O atoms from INAIP ligands and a water molecule in a distorted square-antiprismatic geometry, while the AgI atom has a distorted trigonal-planar AgN2O geometry. Intermolecular O—H...O and N—H...O hydrogen bonds stabilize the crystal structure.
