The structure of di-ortho-tolylmercury has been determined by single crystal X-ray methods from counter data.The compound crystallizes in the monoclinic space group C2/c with unit cell dimensions a 10.970(2), b 10.448(3), c 11.409(3) Angstroem; β 115.48(2) deg, V 1180.5(5) Angstroem³, ρ_calc 2.158 g/cm³ and Z = 4.The structure was solved with conventional heavy atom techniques.The crystal consists of individual molecular units with the mercury atom located on the crystallographic 2-fold axis of symmetry.The C-Hg-C fragment is nearly linear with an angle of 178.0(4) deg.The methyl groups lie on the same side of the molecule and the rings are twisted with respect to one another by 58.9 deg.The Hg-C bond distance is 2.09(1) Angstroem.
