μ-Decane-dioato-bis-[aqua-bis-(1,10-phenanthroline-κN,N')manganese(II)] dinitrate-sebacic acid-water (1/1/2).

In the title complex, [Mn(2)(C(10)H(16)O(4))(C(12)H(8)N(2))(4)(H(2)O)(2)](NO(3))(2)·C(10)H(18)O(4)·2H(2)O, the asymmetric unit contains one-half of the centrosymmetric dinuclear complex cation, one uncoordinated water molecule, one-half of a free sebaic acid (decanedioic acid) molecule that is also completed by inversion symmetry, and one disordered nitrate anion [occupancy ratio 0.454†(4):0.544†(6)]. The Mn(II) atoms are each octa-hedrally surrounded by four N atoms from two 1,10-phenanthroline (phen) ligands, one O atom from one carbonyl group of the bridging sebacate ligand and one O atom of a water mol-ecule. The crystal structure is stabilized by intermolecular O-H⋯O hydrogen bonds.
