Abstract: The asymmetric unit of the title compound, [Fe(C₉H₄O₆)(C₁₂H₈N₂)(H₂O)]_n, contains one Fe^II cation, one 5-carboxybenzene-1,3-dicarboxylate dianion (Hbtc), one 1,10-phenanthroline (phen) ligand and one water molecule. The Fe^II centre displays a distorted octahedral geometry, being surrounded by one phen ligand, two ₂-O atoms of two carboxylate groups from two Hbtc ligands, one O atom from one carboxylate of another Hbtc ligand and one terminal water molecule. One carboxylate group ligates two Fe^II cations in a _1,1 mode, while the other carboxylate groups bonds to only one Fe atom. The crystal structure is stabilized by O-HO hydrogen bonds.
