Abstract: The title compound, {systematic name: (3-carboxy-1-ethyl-6-fluoro-7-piperazin-4-ium-1-yl-1H-quinolin-4-ylidene)oxonium tri-₂-chlorido-bis[trichloridobismuthate(III)] chloride dihydrate], (C₁₆H₂₀FN₃O₃)₂[Bi₂Cl₉]Cl·2H₂O, is composed of [Bi₂Cl₉]^3- anions lying on crystallographic twofold rotation axes, Cl^- anions also on twofold axes, C₁₆H₂₀FN₃O₃²⁺ cations, and water molecules. The Bi^III coordination polyhedron is a distorted octahedron and two such octahedra share a triangular face to form the complex anion. There are three short terminal Bi-Cl bonds [2.5471 (6)-2.5781(5 Å] and three longer bridging bonds [2.8599 (5)-2.9984 (6) Å] in each octahedron. Anions, cations and water molecules are linked by hydrogen bonds to form a three-dimensional network. There are also - stacking interactions between quinoline ring systems, with an interplanar distance of 3.27 (1) Å.
