Abstract
The preparation, X-ray structure, Raman spectrum and conductivity of 4,7,13,16-tetraoxa-1,10-dithiacyclooctadecanebis(diiodine) (2(C12H24O4S2)·5I2) are described. The title compound crystallizes in space group P1 (No. 2) with a=12.467(8), b=14.097(7), c=15.662(9) A; α=75.53(4), β=75.94(5), γ=70.01(4)° and Z=2; R=0.043 for 5899 reflections. The I2 units form a neutral polyhalogen network anchored at sulfurs. The Raman spectrum at 100 K shows one peak at 164 cm−1 assigned to the symmetric stretching mode of I2. This compound has low electrical conductivity, which is attributed to the lack of continuous polyiodide chains in the structure.
