A new compound C₁₇H₂₀FN₃O·CuBr·H₂O is synthesized in the crystal form, where C₁₇H₁₈FN₃O₃ (CfH, ciprofloxacin) is 4-oxo-7-(1-piperazinyl)-6-fluoro-1-cyclopropyl-1,4-dihydroquinoline-3-carboxylic acid. Crystallographic data of ciprofloxacinium tetrabromocuprate(II) monohydrate, C₁₇H₂₂Br₄CuFN₃O₄: a = 8.214(1) Å, b = 10.781(2) Å, с = 13.703(2) Å, α = 85.144(2)°, β = 79.119(2)°, γ = 84.018(2)°, V =
1182.5(4) ų, space group, Z = 2. Supramolecular architecture of the crystal differs from that established for C₁₇H₂₀FN₃O·CuCl·H₂O by the absence of π-π interactions of the aromatic rings of CfH ions and also the structural motifs formed by intermolecular hydrogen bonds.
