In the easily accessible salt [(H 5 O 2 )(db24c8)] 2 [Pd 2 I 6 (I 2 )], iodine molecules are catenated in linear anionic chains [ … I 2 PdI 2 PdI 2 … I–I … ] 2– which are separated by bulky cations consisting of two (H 5 O 2 ) + cations sequestered in dibenzo‐24‐crown‐8 (db24c8) molecules. The new compound is obtained as black single crystals (triclinic, P1, a = 1001.8(2), b = 1185.8(2), c = 1503.7(3) pm, α = 102.97(1), β = 107.65(1), γ = 90.85(1)°, V = 1652.3(5) 10 6 ·pm 3 , Z = 1) from a moist 1:1 dichloromethane/ethanol solution of PdCl 2 , iodine and db24c8.
