Abstract
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 comple x [Hg(2)I(4)L(2)] as one of the products. The crystal structure of thi s compound shows a chelating behaviour of L and different (terminal, a symmetric bridging) iodide coordination modes. Some spectroscopic char acteristics of the dimer and the biological relevance of this reaction are also reported.
