Abstract: The new iodobismuthate compound (C₁₃H₁₁N₂O)₄[Bi₆I₂₂] has been synthesized solvothermally by reacting BiI₃, Zn(NO₃)₂·6H₂O and 4,5-diazafluoren-9-one in a water/ethanol solvent mixture. The asymmetric unit of the compound contains two independent [N-ethyl-4,5-dafo]⁺ cations and one-half of a centrosymmetric [Bi₆I₂₂]^4- anion. The average terminal Bi-I, Bi-₂-I and Bi-₃-I bond lengths in the anion are 2.8923 (2), 3.1403 (2) and 3.3022 (2) Å, respectively.
