Isolated Triiodide and Pentaiodide Anions in the Crystal Structure of [Rb(Dibenzopyridino‐18‐Crown‐6)2]2(I3)(I5)

Red shiny crystals of [Rb(dibenzopyridino‐18‐crown‐6)₂]₂(I₃)(I₅) were obtained from a dichloromethane/ethanol solution of RbI, I₂ and dibenzopyridino‐18‐crown‐6. Triclinic, , a = 1494.3(1), b = 1534.1(1), c = 2412.9(2) pm, α = 76.95(1), β = 83.58(1), γ = 68.67(1)°, V = 5016.7(7) 10⁶·pm³, Z = 2. The crystal structure consists of [Rb(dbp18c6)₂]⁺ cations leaving suitable three‐dimensional channels for the linear I₃⁻ and V‐shaped I₅⁻ anions which are isolated from each other.
