Triaqua(2,2'-bipyridine-kappa2N,N')(nitrato-kappaO)manganese(II) nitrate.

The crystal structure of the title compound, [Mn(NO(3))(C(10)H(8)N(2))(H(2)O)(3)]NO(3), contains a monomeric [Mn(NO(3))(bpy)(H(2)O)(3)]+ cation (bpy is 2,2'-bipyridine) and a nitrate anion. The Mn(II) ion is coordinated by one chelating bpy [Mn-N 2.241 (3) and 2.259 (3) A], three water molecules [Mn-O 2.120 (3)-2.188 (3) A] and a nitrate ligand [Mn-O 2.228 (2) A] in a distorted octahedral geometry. There are O.H-O hydrogen-bonding interactions between the ligated water molecules and the ligated and unligated nitrate anions, resulting in double columns of stacked cations and anions.
