Diaqua-bis-[1-ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxyl-ato]magnesium(II) hexa-hydrate.

In the title compound, [Mg(C16H17FN3O3)2(H2O)2]·6H2O, the Mg2+ ion (site symmetry \overline{1}) exhibits a distorted MgO6 octa­hedral geometry defined by two O,O-bidentate 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazin­yl)-3-quinoline-carb­oxyl­ate (norf) anions and two water mol­ecules. In the crystal, O—H⋯O and O—H⋯N hydrogen bonds help to establish the packing.
