Abstract: In the title compound, {[Mn(C₁₆H₁₈N₃O₃)(C₁₄H₈O₅)]·H₂O}_n, the unique Mn^II ion is coordinated by two O atoms from a chelating 1-ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylate ligand and three O atoms from three 4,4'-oxydibenzoate ligands, forming a distorted square-pyramidal coordination environment. In the crystal structure, centrosymmetric dinuclear manganese units are linked via 4,4'-oxydibenzoate ligands into one-dimensional chains; these chains are, in turn, connected via intermolecular N-HO and O-HO hydrogen bonds to form a two-dimensional supramolecular network. The O atom of the solvent water molecule is disordered over two sites with equal occupancies; the attached H atoms are common to both sites.
