Abstract: In the title compound, {[Fe(CHO₂)₂(C₁₀H₈N₂)(H₂O)]·4H₂O}_n, the Fe^II ion is coordinated by two 4,4'-bipyridyl (4,4'-bpy) ligands, three formate ligands and one water molecule. The slightly distorted octahedral FeN₂O₄ coordination results from the N atoms of two bridging 4,4'-bpy ligands, the O atoms of two bridging HCOO^- anions of anti-anti mode, all in trans positions around the metal centre, and the O atoms of one terminal HCOO^- anion and of one water molecule. The bridging formate ligands link the metal ions into chains that are further connected via 4,4'-bpy ligands into a framework structure. The three-dimensional structure is stabilized by extensive O-HO hydrogen bonding. The crystals were twinned containing a 0.84:0.16 racemate.
