Description
Summary:The title compound, {systematic name: (3-carb­oxy-1-ethyl-6-fluoro-7-piperazin-4-ium-1-yl-1 H -quinolin-4-yl­idene)oxonium tri-μ 2 -chlorido-bis­[trichloridobismuthate(III)] chloride dihydrate], (C 16 H 20 FN 3 O 3 ) 2 [Bi 2 Cl 9 ]Cl·2H 2 O, is composed of [Bi 2 Cl 9 ] 3− anions lying on crystallographic twofold rotation axes, Cl − anions also on twofold axes, C 16 H 20 FN 3 O 3 2+ 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 π–π stacking inter­actions between quinoline ring systems, with an inter­planar distance of 3.27 (1) Å.
