Synthesis, X-ray structure and 199Hg, 77Se CP MAS NMR studies on the first tris(imidazolidine-2-selone) mercury complex: {Chloro-tris[N-methyl-2(3H)-imidazolidine-2- selone]mercury(II)}chloride

A novel cationic Hg(II) complex has been synthesized with N-methyl-imidazolidine-2-selone ligand. The tris(N-methyl-imidazolidine-2-selone) mercury(II) complex, [(MeImSe)3HgCl]+Cl− (1), has been characterized by single crystal X-ray analysis and CP MAS 199Hg and 77Se NMR.
