Abstract

Hg(II) complexes with tris (6-methyl-2-pyridylmethyl)-amine (L1), 6-methyl-N(2-mercaptoethyl)picolylamine (HL2) and 2,6-bis(pyridyl-2-methythiomethyl)pyridine (HL3) have been synthesized and characterized by measurements of 1H NMR The molecular structures of [Hg(L1)(NO3)2] (1) and [Hg3(HL2) 3](ClO4)3 (3) were determined by single-crystal X-ray structure analysis and a disordered crystal was obtained from crystallization of L3 with CdCl2. In complex 1, the Hg(II) metal center has three strong bonds to ligand nitrogen, a weak bond to the third pyridyl, and two bidentate nitrates.. Complex 3 contains Hg(II) coordinated with the NN'S donor set from ligand HL2 with the thiolates of each ligand bridging to a second metal center. 3 forms a novel trinulcear complex with a three-fold symmetric (HgS)3 core. Variable temperature 1H NMR of 3 showed slow intramolecular ligand exchange on the J(1H1H) time scale. Further analysis and additional studies at higher temperature of 3 are planned to study dissociation or alternative oligomers.
