The title compound, [Zn(C17H19FN3O3)2(H2O)]·2H2O or [Zn(pef)2(H2O)]·2H2O, where pef is 1-ethyl-6-fluoro-7-(4-methylpiperazin-4-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylate, was synthesized under hydrothermal conditions. The ZnII atom exhibits a distorted ZnO5 square-pyramidal geometry defined by two bidentate O,O-bonded pef anions in the basal plane and one water molecule in the apical position. A network of O—H⋯O and O—H⋯N hydrogen bonds is formed between the ZnII complexes and the uncoordinated water molecules.

A mixture of Zn(CH3COO)2.2H2O (0.055 g, 0.25 mmol), Hpef (0.17 g, 0.5 mmol) and water (12 ml) was stirred for 30 min in air. The mixture was then transferred to a 23 ml Teflon-lined hydrothermal bomb. The bomb was kept at 433 K for 72 h under autogenous pressure. Upon cooling, colorless prisms of the title compound were obtained from the reaction mixture.
All H atoms on C atoms were generated geometrically and refined as riding atoms with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C). H atoms of the coordinated water molecule were located from difference Fourier maps and refined with distance restraints of d(O—H) = 0.82 (1) Å and d(H···H) = 1.35 Å. H atoms of the lattice water molecules were placed so as to form a reasonable H-bond network and were refined as riding. Their positions are uncertain.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |

Pefloxacin (Hpef, C17H20FN3O3, 1-ethyl-6-fluoro-7-(4-methylpiperazin-1-yl)-4-oxo-quinoline-3-carboxylic acid) is member of a class of quinolones used to treat infections (Mizuki et al., 1996). The silver(I), manganese(II) and cobalt(II) complexes of the pefloxacin (pef) anion have been reported (Baenziger et al., 1986; An, Huang & Qi, 2007; An, Qi & Huang, 2007). The title zinc(II) complex is reported here.
The title structure of is built up from Zn2+ cations, pef ligands, one coordinated water molecule, and two uncoordinated water molecules (Fig. 1). The coordination geometry around ZnII is a slightly distorted square pyramid (Table 1). The components of the structure are linked by O—H···O and O—H···N hydrogen bonds involving all the potential donors (Table 2).
