title: Di-μ-sulfato-bis-[diaqua-(1H-imidazo[4,5-f][1,10]phenanthroline)iron(II)] dihydrate.
abstract: 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.
