Bis(piperazine-1,4-diium) hexachloridobismuthate(III) chloride monohydrate

Abstract

The crystal structure of the title compound, (C4H12N2)2[BiCl6]Cl·H2O, consists of piperazinediium cations, [BiCl6]3− anions, Cl− anions and uncoordinated water molecules. The BiIII cation is coordinated by six Cl− anions in a slightly distorted octahedral geometry. The diprotonated piperazine ring adopts a chair conformation. In the crystal, extensive intermolecular N—H...Cl, N—H...O and O—H...Cl hydrogen bonds occur.
