Diaquabis[1-ethyl-6-fluoro-7-(4-methylpiperazin-4-ium-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylato-²O³,O⁴]manganese(II) benzene-1,4-dicarboxylate tetradecahydrate

Abstract: In the title compound, [Mn(C₁₇H₂₀FN₃O₃)₂(H₂O)₂](C₈H₄O₄).14H₂O, the Mn^II atom (site symmetry $\\overline{1}$ ) exhibits a distorted MnO₆ octahedral geometry defined by two neutral bidentate O,O-bonded 1-ethyl-6-fluoro-7-(4-methylpiperazin-4-ium-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylate (Hpef) zwitterions and two water molecules. The charge-balancing benzene-1,4-dicarboxylate (1,4-bdc) anion is also centrosymmetric. An extensive network of O-HO and O-HN hydrogen bonds helps to establish the crystal packing.
