Bis(μ-2-carboxymethyl-2-hydroxy-butane-dioato)bis-[diaqua-manganese(II)]-1,2-bis-(pyridin-4-yl)ethane-water (1/1/2).
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].
