| Abstract: | Octafluorobiphenylene was made by heating 1,2-diiodotetrafluorobenzene in a sealed, evacuated tube with either copper, lead or bismuth. The crystal used for the diffraction studies was grown from hexane. Crystal data: C12F8, Mr = 296.116, monoclinic, A2/a, a = 21.140(2), b = 6.430(6), c = 36.340(3) ÅA, β = 123.76(3)°, U = 4106.73 ÅA3, Z = 16, Dm = 1.884 g cm−3, Dx = 1.907 g cm−3, λ(Cuka) = 1.5418 ÅA, μ = 1.810 mm−1, F(000) = 2304, measurement temperature = 293K, R = 0.059 for 2230 reflections with I > 3σ(I). |
