Abstract: In the title compound, {[Cu(C₁₆H₁₇FN₃O₃)₂]·4H₂O}_n, the Cu^II atom is bonded to two O,O'-bidentate 1-ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylate (norf) monoanions and a symmetry-generated N-bonded norf anion, resulting in a distorted square-pyramidal coordination environment with the N atom occupying the apical site. The bridging norf anion results in one-dimensional chains propogating along [010]. A network of O-HO and N-HO hydrogen bonds helps to establish the crystal structure.
