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-H...O hydrogen bonds, forming a three-dimensional supramolecular structure. Parts of the nicotinic acid derivative are equally disordered over two sets of sites.
