The title dinuclear FeII complex, [Fe2(SO4)2(C13H8N4)2(H2O)4]·2H2O, is centrosymmetric. Two sulfate anions bridge two FeII cations to form the binuclear complex. Each FeII 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 molecules in a distorted octahedral geometry. Extensive O—H⋯O, N—H⋯O and O—H⋯N hydrogen bonding is present in the Weak π–π stacking is observed between parallel IP ring systems, the face-to-face separation being 3.428 (14) Å.

The IP was synthesized according to reference of Wu et al. (1997). A mixture of FeSO4.7H2O, benzene-1,4-dicarboxylic acid, IP and H2O in a molar ratio 1:1:1:556 was stirred for 1 h, then sealed in an 18 ml Teflon-lined stainless steel reactor and heated for 3 d at 433 K and autogeneous pressure. After allowing the reaction mixture to cool down to room temperature, yellow crystals were obtained.
Water H atoms were located in a difference Fourier map and refined isotropically with restrained O—H distance = 0.84 (1) Å and H···H distance = 1.44 (1) Å. The other H atoms were generated geometrically with C—H = 0.93 and N—H = 0.86 Å, Uiso(H) = 1.2Ueq(C,N).
Transitional metal complexes of 1,10-Phenanthroline's derivatives still continue to attract intense interest not only because of their fascinating architectures but also because of the intriguing properties, such as magnetic, biological activity and optical properties. The IP ligand,as one of 1,10-Phenanthroline's derivatives, has recently gained a lot of interest with respect to synthesis of its novel metal compounds. It has been used to construct coordination frameworks by the direct interaction with metal ions or as secondary ligands to form discrete polynuclear, one-dimensional, two-dimensional and three-dimensional coordination networks. Its metal complexes are focused on Ru, Co, Ni, Cd, Cu, Mn and Zn complexes (Liu et al., 2009; Stephenson et al., 2008; Wu et al., 1997; Yang et al., 2010; Yu, 2009;). As an extension of the work on the structural characterization of IP complexes, the preparation and
of the title FeII complex is reported here.In centrosymmetric dinuclear complex, the sulfate acts as an O—S—O bridge across two FeII cation, determining the formation of a dimer (Fig. 1).The FeII cation has a distorted octahedral coordination completed by two nitrogen atoms from one IP ligand, two oxygen atoms from water and two oxygen atoms from two sulfuric anions. The equatorial plane of the octahedron is defined by N1, O6, O2, O5 around Fe1, and the axial coordination sites are occupied by N2 and O1 atoms.
Strong hydrogen bonds exist in the structure (Table 2). The complicated three-dimensional hydrogen bonding network is shown in Fig. 2. The uncoordinated water molecular is a hydrogen bond acceptor from the coordinated water and a hydrogen bond donor to two O atoms of two sulfuric anions in two neighboring [Fe2(SO4)2(IP)2(H2O)2] species. The [Fe2(SO4)2(IP)2(H2O)2] molecules also form hydrogen bonds between themselves through O—H···N and N—H···O interactions from the imidazolyl ring. So [Fe2(SO4)2(C13H8N4)2(H2O)2] molecules and the uncoordinated water are connected by O—H···O, O—H···N and N—H···O hydrogen bonds into a three-dimensional network structure. There is also a π-π stacking interaction between the IP ligands of the neighboring [Fe2(SO4)2(IP)2(H2O)2] species with an interplanar separation of about 3.428 (14) Å [symmetry code = -x, 2 - y, -z].

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Transitional metal complexes of 1,10-Phenanthroline's derivatives still continue to attract intense interest not only because of their fascinating architectures but also because of the intriguing properties, such as magnetic, biological activity and optical properties. The IP ligand,as one of 1,10-Phenanthroline's derivatives, has recently gained a lot of interest with respect to synthesis of its novel metal compounds. It has been used to construct coordination frameworks by the direct interaction with metal ions or as secondary ligands to form discrete polynuclear, one-dimensional, two-dimensional and three-dimensional coordination networks. Its metal complexes are focused on Ru, Co, Ni, Cd, Cu, Mn and Zn complexes (Liu et al., 2009; Stephenson et al., 2008; Wu et al., 1997; Yang et al., 2010; Yu, 2009;). As an extension of the work on the structural characterization of IP complexes, the preparation and crystal structure of the title FeII complex is reported here.
In centrosymmetric dinuclear complex, the sulfate acts as an O—S—O bridge across two FeII cation, determining the formation of a dimer (Fig. 1).The FeII cation has a distorted octahedral coordination completed by two nitrogen atoms from one IP ligand, two oxygen atoms from water and two oxygen atoms from two sulfuric anions. The equatorial plane of the octahedron is defined by N1, O6, O2, O5 around Fe1, and the axial coordination sites are occupied by N2 and O1 atoms.
Strong hydrogen bonds exist in the structure (Table 2). The complicated three-dimensional hydrogen bonding network is shown in Fig. 2. The uncoordinated water molecular is a hydrogen bond acceptor from the coordinated water and a hydrogen bond donor to two O atoms of two sulfuric anions in two neighboring [Fe2(SO4)2(IP)2(H2O)2] species. The [Fe2(SO4)2(IP)2(H2O)2] molecules also form hydrogen bonds between themselves through O—H···N and N—H···O interactions from the imidazolyl ring. So [Fe2(SO4)2(C13H8N4)2(H2O)2] molecules and the uncoordinated water are connected by O—H···O, O—H···N and N—H···O hydrogen bonds into a three-dimensional network structure. There is also a π-π stacking interaction between the IP ligands of the neighboring [Fe2(SO4)2(IP)2(H2O)2] species with an interplanar separation of about 3.428 (14) Å [symmetry code = -x, 2 - y, -z].
