The 2 : 1 and 1 : 1 reactions of MeHgI with 2-(2′-pyridyl)quinoxaline (L) in methanol led to Hg - C bond cleavage and yielded the dinuclear complex [Hg2I4L2] as one of the products. The crystal structure of this compound shows a chelating behaviour of L and different (terminal, asymmetric bridging) iodide coordination modes. Some spectroscopic characteristics of the dimer and the biological relevance of this reaction are also reported.
