【 摘 要 】

A reaction of YI₃, dibenzo-24-crown-8 and iodine in ethanol yielded, as a by-product, red single crystals of (I₂)@(db24c8). In the triclinic crystal, P-1, a = 485.0(1), b = 1203.7(3), c = 1280.4(2) pm, a = 64.56(2)°, β = 86.82(2)°, γ = 83.89(2)°, V = 671.1(2) × 10^6.pm³, Z = 1, R₁= 0.0301 for 1965 reflections with I₀ > 2σ(I₀), iodine molecules with an I–I distance of 268.39(7) pm, slightly longer than in the gas phase, are included in a matrix of db24c8 molecules.
