Crystal structure of catena-poly[[[tetra-aqua-iron(II)]-trans-?-1,2-bis-(pyridin-4-yl)ethene-?2N:N'] bis-(p-toluene-sulfonate) methanol disolvate].

ABSTRACT: 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 mol-ecules in the equatorial positions and two 1,2-bis-(pyridin-4-yl)ethene mol-ecules in the axial positions. This results in a distorted octa-hedral geometry for the [N2O4] coordination polyhedron. The 1,2-bis-(pyridin-4-yl)ethene mol-ecules 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 mol-ecules as donors towards the O atoms of the methanol mol-ecules and tosyl-ate anions as acceptors of protons, leading to the formation of a three-dimensional supra-molecular network. Weak C-H?O hydrogen bonds are also observed in the crystal.
