چکیده
The title compound, C(21)H(18)O(3)S, is the E isomer, the ester -oxy link being trans to one of the phenyl groups. The planes of the phenyl substituents at the vinyl C atoms form a dihedral angle of 66.32 (7)° with each other. The vinyl group shows noticeable non-planarity, the C(Ph)-C=C-C(Ph) torsion angle being 8.4 (3)°.

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-ec...

The asymmetric unit of the title salt, C6H8NO(+)·C7H7O3S(-), contains two cations and two anions. In the crystal, the cations and anions are linked through extensive N-H⋯O and O-H⋯O hydrogen-bonding inter-actions, which result in R 4 (4)(18) and R 2 (1)(4) ring motifs, forming a three-dimensional network.
