The title compound, [Ag(L)]·H2O, 1, where HL=4-(isonicotinamido)benzoic acid, was synthesized in methanol solution and its crystal structure was determined by X-ray diffraction analysis. The crystal is of monoclinic, space group P21/c with a=0.571 8(8) nm, b=1.357 2(18) nm, c=1.558 0(2) nm, β=91.090(2)°, V=1.209 0(3) nm3, Z=4, Dc=2.009 g·cm-3, F(000)=722, Rint=0.042 9, R=0.027 1, wR=0.055 6. In complex 1, the Ag atoms are linearly coordinated by one O atom and one N atom of two ligand molecules. Each L-ligand in turn uses its one carboxylate group and one pyridinyl groups to connect two metal centers, then the one-dimensional (1D) chains is formed. On the other hand, the 1D chains are further connected by O1W-H1WB…O2 hydrogen bonds and Ag-O weak interactions to give a two-dimensional (2D) layer, finally, the 2D net extents to three-dimensional (3D) supramolecular framework by O1W-H1WB…O1 as well as N2-H2…O2 interactions.
