چکیده
The asymmetric unit of the title compound, [Mn(2)(C(6)H(6)O(7))(2)(H(2)O)(4)]·C(12)H(12)N(2)·2H(2)O, comprises half of a centrosymmetric dimer, half of a 1,2-bis-(pyridin-4-yl)ethane and one water mol-ecule. Two citrate ligands bridge two Mn(II) ions, the Mn(II) ion being coordinated by four O atoms from the citrate(2-) ligands and two water O atoms, forming a distorted octa-hedral environment. In the crystal, O-H⋯O 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 = 3.792 (2) Å].

The title compound, {[Fe(NCSe)2(C12H12N2)(H2O)2]·2C12H12N2·2H2O} n , was obtained by the reaction of iron(II) sulfate hepta-hydrate and potassium seleno-cyanate with 1,2-bis-(pyridin-4-yl)ethane (bpa) in water. The Fe(II) cation is coordinated by two N-bonded seleno-cyanate anions, two water mol-ecules and two 1,2-bis-(pyridin-4-yl)ethane (bpa) ligands in a slightly distorted octa-hedral geomet...
