【 摘 要 】

In the title polymeric complex, {[Fe(C12H10N2)2(H2O)4](CH3C6H4SO3)2·2CH3OH}n, the FeII cation, located on an inversion centre, is coordinated by four water mol­ecules in the equatorial positions and two 1,2-bis­(pyridin-4-yl)ethene mol­ecules in the axial positions. This results in a distorted octa­hedral geometry for the [N2O4] coordination polyhedron. The 1,2-bis­(pyridin-4-yl)ethene mol­ecules bridge the FeII cations, forming polymeric chains running along the a-axis direction. Stabilization of the crystal structure is provided by O—H⋯O hydrogen bonds; these are formed by coordinated water mol­ecules as donors towards the O atoms of the methanol mol­ecules and tosyl­ate anions as acceptors of protons, leading to the formation of a three-dimensional supra­molecular network. Weak C—H⋯O hydrogen bonds are also observed in the crystal.
