摘要

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—H⋯O and N—H⋯O hydrogen bonds helps to establish the crystal structure.
