Figure 1 The structure of the title compound showing the atom numbering scheme. Displacement ellipsoids are shown at the 50% probability level. The labelled atoms are related to unlabelled atoms by the symmetry codes: [1 - x, 1 - y, 1 - z] for diaqua-bis-(citrato)di-manganese(II) complex and [2 - x, 2 - y,z] for the 1,2-bis(pyridin-4-yl)ethene molecule.  [article HTML]
