Diaqua­bis(norfloxacinato)manganese(II) 2,2′-bipyridine solvate tetra­hydrate

In the crystal structure of the title compound {systematic name: diaqua­bis[1-ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydro­quinoline-3-carboxyl­ato]manganese(II) 2,2′-bipyridine solvate tetra­hydrate}, [Mn(C(16)H(17)FN(3)O(3))(2)(H(2)O)(2)]·C(10)H(8)N(2)·4H(2)O, the pyridone O atom and one carboxyl­ate O atom of the two norfloxacin ligands are bound to the Mn(II) ion, which is located on an inversion centre, and occupy equatorial positions, while two aqua O atoms lie in apical positions, resulting in a distorted octa­hedral geometry. The crystal packing is stabilized by N—H⋯O and O—H⋯O hydrogen-bonding interactions.
