Bis[methylmercury(II)] complexes have been prepared with the potentially bidentate dithiol ligands trans-1,2-dimercaptocyclohexane (1), 3,4-dimercaptotoluene (2), and endo,cis-2,3-dimercaptobicyclo[2.2.1]heptane (3). The crystal structure of [Hg2Me2L][L =(1)] has been determined by X-ray diffraction. The crystals are monoclinic, space group P21/c, with a= 9.609(3), b= 13.428(3), c= 10.268(3), β= 112
