Abstract The compounds 4,4′-bipyridinium(2+) pentachloro-bismuthate(III) (1), [4,4′-(C10H8N2)BiCl5] and 2,2′-bipyridinium(2+) pentachloro-bismuthate(III) (2), [2,2′-(C10H8N2)Bi2Cl10] have been obtained by reacting bismuthate oxide and 4,4′-bipyridine or 2,2′-bipyridine in HCl acid medium. They have been characterized by single crystal X-ray analysis. (1) crystallizes in the triclinic space group $$P\bar 1$$ with a = 9.776(2), b = 11.009(3),c = 8.346(1) Å, α = 101.58(2), β = 98.63(2), and γ = 112.86(2)°. (2) crystallizes in the monoclinic space group P21/c with a = 14.239(2), b = 14.226(2), c = 16.275(3) Å, and β = 110.15(2)°. The crystal structure of (1) consists of 4,4′-bipyridinium(2+) cations interacting through hydrogen bonding with [Bi2Cl10]2− dimers giving rise to endless double chains, while that of (2) is formed by 2,2′-bipyridinium(2+) cations and [Bi4Cl20]8− tetramers extensively interacting through hydrogen bonding. The different polynuclearity of the anions seems related to the different directions along which each cation can form hydrogen bond interactions.
