Abstract: The dinuclear title complex, [Ag₂(NO₃)₂(3-PyOH)₄]·2H₂O (3-PyOH is 3-hydroxypyridine, C₅H₅NO), situated across a crystallographic inversion centre, can be described as a dimeric structure, in which two [Ag(3-PyOH)₂] groups are held together by the AgAg interaction [3.317 (1) Å]. Each Ag atom is two-coordinate and exists in an approximately linear geometry. The two NO₃^- ions interact with the Ag^I atoms in a bridging mode through very weak AgO interactions [AgO = 2.862 (2) and 2.877 (2) Å]. A three-dimensional supramolecular framework is formed by O-HO hydrogen bonds.
