The new iodobismuthate compound (C13H11N 2O)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 - μ2-I and Bi - μ3-I bond lengths in the anion are 2.8923 (2), 3.1403 (2) and 3.3022 (2) Å, respectively. © 2006 International Union of Crystallography All rights reserved.
