چکیده
The asymmetric unit of the title compound, [Mn2(C6H6O7)2(H2O)4]·C12H10N2·2H2O, contains half of the centrosymmetric Mn complex dimer, half of a 1,2-bis-(pyridin-4-yl)ethene mol-ecule, which lies across an inversion center, and one water mol-ecule. Two citrate ligands bridge two Mn(II) ions, and each Mn(II) atom is coordinated by four O atoms from the citrate ligands (one from hy-droxy and three from carboxyl-ate groups) and two water O atoms, forming a distorted octa-hedral environment. In the crystal, O-H⋯O and O-H⋯N hydrogen bonds link the centrosymmetric dimers and lattice water mol-ecules into a three-dimensional structure which is further stabilized by inter-molecular π-π inter-actions [centroid-centroid distance = 3.959 (2) Å]. Weak C-H⋯O hydrogen bonding interactions are also observed.

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...
