title: Diaqua-bis(norfloxacinato)manganese(II) 2,2'-bipyridine solvate tetra-hydrate.
abstract: In the crystal structure of the title compound {systematic name: diaqua-bis[1-ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydro-quinoline-3-carboxyl-ato]manganese(II) 2,2'-bipyridine solvate tetra-hydrate}, [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 carboxyl-ate 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 octa-hedral geometry. The crystal packing is stabilized by N-H⋯O and O-H⋯O hydrogen-bonding interactions.
