Abstract: The reaction of silver formate with HCO₂H and 4,4'-bipyridine in CH₃CN produced the title compound, [Ag(CHO₂)(C₁₀H₈N₂)]·H₂O·CH₂O₂. In the structure, each 4,4'-bipyridine moiety acts as a bidentate ligand that binds two Ag atoms, thus forming a linear chain. The formate ions bridge the adjacent chains through Ag-O bonds [Ag-O = 2.709 (6)-3.089 (5) Å] to form molecular ladders. The molecular ladders are stacked into layers and are interconnected by O-HO hydrogen bonds.
