Abstract

Abstract Reactions of [(HgR)(CF 3SO 3)] (R = CH 3 or C 6H 5) with tris(2-dimethylaminoethyl)amine (trenMe 6) give the complexes [(trenMe 6)HgR][CF 3SO 3). These have been characterized by 1H and 13C{ 1H} NMR spectroscopy and the complex formation equilibria in aqueous solution between methylmercury(II) ion and trenMe 6 have been investigated. A complete X-ray analysis of the phenylmercury derivative has been carried out. The complexes appear to be five-coordinate both in the solid state and in organic solvents; potentiometric investigations also support strongly the total coordination of trenMe 6 to methyl-mercury(II) in aqueous solution.
