Abstract: In the title binuclear complex, [Fe₂(C₈H₇O₂)₄(C₁₂H₈N₂)₂(H₂O)], the Fe^II ion is six-coordinated by three carboxylate O atoms from three 4-methylbenzoate ligands, two N atoms from two 1,10-phenanthroline ligands and one bridging aqua ligand in a distorted octahedral geometry. The coordinated water molecule acting as the bridging ligand is located on a twofold axes and the complex molecule displays C₂ molecular symmetry. The FeFe separation in the binuclear complex is 3.490 (3) Å. The crystal structure is stabilized by hydrogen bonding and - stacking interactions [the centroid-centroid distance between adjacent 1,10-phenanthroline ring systems is 3.653 (2) Å, and that between the 1,10-phenanthroline ring system and the phenyl ring of the 4-methylbenzoate unit of a neighbouring complex is 3.622 (3) Å].
