Abstract: In the title compound, {[Co(C₁₆H₁₇FN₃O₃)₂]·2H₂O}_n, the Co atom exists in a distorted trans-CoN₂O₄ octahedral geometry that is defined by two monodentate N-bonded and two bidentate O,O'-bonded 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazinyl)-3-quinoline carboxylate ligands. The extended two-dimensional structure exhibits a 13.33 × 16.19 Å square grid. The Co atom lies on a center of inversion.
