The title compound {systematic name: tetrakis[4-(3-carboxy-1-ethyl-6-fluoro-4-hydroxonio-1,4-dihydro-7-quinolyl)-1-methylpiperazin-1-ium] di-μ2-chlorido-bis[tetrachloridobismuthate(III)] tetrachloride octahydrate}, (C17H22FN3O3)4[Bi2Cl10]Cl4·8H2O, is composed of edge-shared centrosymmetric dinuclear [Bi2Cl10]4− anions, Cl− anions, dihydrogen pefloxacinium cations and water molecules. The BiIII is a distorted octahedron. There are four short terminal Bi—Cl bonds [2.5037 (10)–2.6911 (7) Å] and two longer bridging bonds [2.8834 (8) and 3.0687 (9) Å] in each octahedron. Two sets of chloride ions and water molecules are disordered over the same sites with site occupancies of 1/3 and 2/3, respectively. Anions, cations and water molecules are linked by O—H⋯O, O—H⋯Cl and N—H⋯Cl hydrogen bonds, forming a three-dimensional framework. There are also π–π stacking interactions between quinoline ring systems [centroid–centroid distance = 3.575 (1) Å].

Bi(OH)3 (1.00 g, 3.85 mmol) was reacted with pfH (1.50 g, 5.77 mmol) in a solution of HCl (35%, 15 ml). Yellow crystals were obtained after evaporation for 72 h at room temperature.
H atoms of H2O were located in a difference map and refined with Uiso(H) = 1.5Ueq(O) and the O-H distances were restrained to be similar. The other H atoms were positioned with idealized geometry using a riding model with C-H = 0.95, 0.98 and 0.99 Å; N-H = 0.93 Å and O-H = 0.84 Å. All H atoms were refined with Uiso set to 1.2 or 1.5 times Ueq of the parent atom. Atoms Cl6 and O6, and also Cl7 and O7, are disordered between them with site occupancies of 1/3 and 2/3, respectively. H atoms belonging to the disordered water molecules could not be located. The maximum peak and the deepest hole are located 0.86 Å and 1.13 Å from Bi, respectively.

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. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Pefloxacin (pfH) belongs to the second-generation quinolone antimicrobial agents. According to a search of the Cambridge Structural Database (CSD, Version 5.28; Allen, 2002), well determined structures are those where pefloxacin acts as an anion or as a single protonated cation. The present research deals with the synthesis and structure of a chlorido-bismuth complex with the doubly protonated cation of pefloxacin (pfH3)2+.
The asymmetric unit of the title compound, (I), contains one Bi atom, seven chlorine atoms (two of them are disordered), one pfH3 cation and three H2O molecules (from them a two are disordered). The Bi atoms are coordinated by six Cl atoms in a distorted octahedral geometry. Two Bi-centred octahedra are linked by double Cl bridges to form a centrosymmetric dinuclear [Bi2F10]4- complex (Fig. 1), with a Bi···Bii distance of 4.4596 (5) Å. In the Bi-octahedra there are four short terminal Bi—Cl bonds [2.5037 (10)-2.6911 (7) Å] and two longer bridging bonds [2.8834 (8) and 3.0687 (9) Å]. These Bi-anions pack up in columns parallel to the [0 0 1] direction (Fig. 2).
The protonation of pfH32+ is realised on the carbonyl atom O3 and N2 of the piperazine ring (Fig. 3). The hydrogen atom H3 is linked by an intramolecular hydrogen bond with O1 atom of the carboxyl group. Atoms O2 and N2 in the cation act as hydrogen-bond donors, via H4 and H2
There are three uncoordinated chlorine atoms (Cl5, Cl6 and Cl7) of which Cl6 and Cl7 are disordered and statistically replaced by atoms O6 and O7 of water molecules, respectively [Wyckoff positions 8j and 4i for Cl6/O6 and Cl7/O7, respectively]. Site occupation factors of these chloride ions were assigned equal to 1/3, and water molecule to 2/3 from the crystal chemistry considerations. The refinement of the Cl6/O6 and Cl7/O7 site occupation factors resulted in the same values with accuracy within 0.04. As the hydrogen atoms were not located for disordered water molecules, probable hydrogen bonds involving these atoms are given in Table 3.
In the crystal structure, the cations are packed along the aaxis. There exist π–π stacking interactions between quinoline ring systems (Fig.4), with nearest C···C contacts are in the range 3.292 (5)-3.365 (3) Å. Anions, cations and H2O-molecules are linked by a network of O—H···O, O—H···Cl and N—H···Cl hydrogen bonds into a three-dimensional framework.
