Abstract: In the title mononuclear complex, [Ag(C₁₂H₈N₄O)₂]NO₃·H₂O, the Ag^I ion is coordinated linearly by two pyridyl N atoms from two crystallographically independent monodentate 2,5-di-4-pyridyl-1,3,4-oxadiazole (4-bpo) ligands. In addition, the asymmetric unit contains one nitrate anion and one solvent water molecule. In the crystal structure, nitrate anions connect to Ag^I ions via weak AgO interactions [AgO = 2.836 (3) Å] and to two symmetry-related solvent water molecules via O-HO hydrogen bonds, to afford a one-dimensional herring-bone-like motif along [100]. Significant - stacking interactions [CgCg = 3.614 (2)-3.721 (2) Å, where Cg is the centroid of a pyridyl or oxadiazole ring] are also found between two adjacent one-dimensional motifs, resulting in a double-strand supramolecular array.
