The structure of [C₁₂H₁₄N₂]₃[BiCl₆]₂ · 2H₂O at room temperature

Abstract

Abstract At room temperature, tris(1,1′-dimethyl-4,4′-bipyridinium) bishexachlorobismuthat(3-) dihydrate, [C 12 H 14 N 2 ] 3 [BiCl 6 ] 2 · 2H 2 O, crystallizes in the triclinic space group C i 1 ; P [unk]; (No. 2) with a = 797.0(2) pm, b = 1215.8(2) pm, c = 1303.9(3) pm, α = 88.76(1)°, β = 83.01(1)°, γ = 73.86(1)°, Z = 1, D x = 1.977 g/cm 3 . The cell contains three [C 12 H 14 N 2 ] 2+ cations (methyl viologen), two slightly distorted BiCl 6 octahedra ([unk] Bi–Cl = 269.4(2) pm) and two water molecules.
