Abstract: The structure of the title compound, (AETO)₄[Pb₃I₁₀] or (C₁₅H₁₄NO₂S)₄[Pb₃I₁₀], contains chains of octahedrally coordinated PbI₆ species along with two crystallographically independent AETO cations that hydrogen bond to these chains. Individual (Pb₃I₁₀)_n^4n- chains are linked into layers via hydrogen bonds. The cations sheath each layer of chains, forming cation-chain-cation triple layers. Cations on adjacent triple layers interdigitate, forming stacks running parallel to [110]. There is a range of hydrogen bonding interactions between each cation and the (Pb₃I₁₀)_n^4n- chains.
