چکیده
The title compound {systematic name: tetra-kis[4-(3-carb-oxy-1-ethyl-6-fluoro-4-hydroxonio-1,4-dihydro-7-quinol-yl)-1-meth-yl-piperazin-1-ium] di-μ(2)-chlorido-bis-[tetra-chlorido-bismuth-ate(III)] tetra-chloride octa-hydrate}, (C(17)H(22)FN(3)O(3))(4)[Bi(2)Cl(10)]Cl(4)·8H(2)O, is composed of edge-shared centrosymmetric dinuclear [Bi(2)Cl(10)](4-) anions, Cl(-) anions, dihydrogen pefloxacinium cations and water mol-ecules. The Bi(III) coordination polyhedron is a distorted octa-hedron. 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 octa-hedron. Two sets of chloride ions and water mol-ecules are disordered over the same sites with site occupancies of 1/3 and 2/3, respectively. Anions, cations and water mol-ecules 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 inter-actions between quinoline ring systems [centroid-centroid distance = 3.575 (1) Å].
