Abstract: In the title compound, {[Fe(C₁₀H₈N₂)₂(H₂O)₂](C₁₂H₇N₂O₄S₂)₂}_n, synthesized by hydrothermal reaction, the 4,4'-bipyridyl ligands (one with symmetry 2, one with symmetry $\\overline1$ ) connect Fe²⁺ cations, forming a cationic layer parallel to (001). The coordination of the Fe²⁺ cation (site symmetry 2) is octahedral, with four N atoms from four 4,4'-bipyridyl ligands and O atoms from two trans water molecules. Adjacent layers are linked with each other by intermolecular O-HO hydrogen bonds, forming a three-dimensional supramolecular structure. Parts of the nicotinic acid derivative are equally disordered over two sets of sites.
