Abstract: In the title compound, [Co(C₁₇H₁₉FN₃O₃)₂(H₂O)₂]·8H₂O, the Co^II atom (site symmetry $\\overline{1}$ ) exhibits a distorted octahedral geometry that is defined by two bidentate O,O-bonded 1-ethyl-6-fluoro-7-(4-methylpiperazin-4-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylate (pef) monoanions and two water molecules. A network of O-HO and O-HN hydrogen bonds help to establish the crystal packing.
