The title dinuclear Fe(II) complex, [Fe(2)(SO(4))(2)(C(13)H(8)N(4))(2)(H(2)O)(4)]·2H(2)O, is centrosymmetric. Two sulfate anions bridge two Fe(II) cations to form the binuclear complex. Each Fe(II) cation is coordinated by two N atoms from a 1H-imidazo[4,5-f][1,10]phenanthroline (IP) ligand, two O atoms from two sulfate anions and two water mol-ecules in a distorted octa-hedral geometry. Extensive O-H⋯O, N-H⋯O and O-H⋯N hydrogen bonding is present in the crystal structure. Weak π-π stacking is observed between parallel IP ring systems, the face-to-face separation being 3.428 (14) Å.
标题为双核铁（II）配合物[Fe₂(SO₄)₂(C₁₃H₈N₄)₂(H₂O)₄]·2H₂O，具有中心对称性。两个硫酸根阴离子桥连两个铁（II）阳离子形成双核配合物。每个铁（II）阳离子由来自1H - 咪唑并[4,5 - f][1,10]菲咯啉（IP）配体的两个N原子、来自两个硫酸根阴离子的两个O原子以及两个水分子配位，呈扭曲的八面体几何构型。晶体结构中存在广泛的O - H⋯O、N - H⋯O和O - H⋯N氢键。在平行的IP环体系之间观察到弱的π - π堆积，面对面间距为3.428（14）Å。
