Summary

The X-ray crystal structure of the title compound, [Hg2(C16H20N2S2)I4], has been determined. The crystals are monoclinic (space groupP21/c), with cell dimensionsa=15.016(2),b=6.201(3),c=15.273(2) Å,β=115.18(1)°;V o =1287.0(7) Å3,M r =1213.266,Z=4,D x =6.26mg m−3, MoKα radiation (graphite crystal monochromator,\(\bar \lambda = 0.71070 {\AA}\)),μ(MoKα)=336 cm−1,F(000)=4272, andT=290°K. The final conventionalR factor=0.054, andR w =0.062 for 2799 observed reflections. The structure was solved by Patterson and Fourier methods and refined by block-diagonal least-squares methods. The coordination around the mercury atoms is approximately tetrahedral, although with considerable distortion, with two iodine atoms and the N and S atoms of one-half of the ligand molecule.
