Abstract: The title salt, (C₄H₁₂N₂)₂[Bi₂Cl₇I₃]·4H₂O, was prepared by the reaction of bismuth trichloride, potassium iodide and piperazine in a hydrochloric acid medium. It is composed of piperazinium dications and dimeric [Bi₂Cl₇I₃]^4- tetraanions, together with water of crystallization. The halobismuthate(III) tetraanion is located on a center of inversion. Hydrogen bonds, including N-HO, N-HCl, N-HI, O-HO, O-HCl and O-HI interactions, are present in the crystal structure.
