摘要

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 C 2 mol­ecular symmetry. The Fe⋯Fe separation in the binuclear complex is 3.490 (3) Å. The crystal structure is stabilized by hydrogen bonding and π–π 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].
