Synthesis and structural characterization of mercury(II) metal complexes containing the 2-(Me2NCH2)C6H4Se ligand

Abstract

The heteroleptic mercury(II) complex [HgCl{SeC 6 H 4 (CH 2 NMe 2)-2}] (1) was prepared by reacting the corresponding lithium organoselenolate in an equimolar ratio with HgCl 2. The complex [Hg(SCN){SeC 6 H 4 (CH 2 NMe 2)-2}] (2) was prepared by the salt metathesis reaction between 1 and KSCN in a 1:1 molar ratio. The metal complexes were characterized in solution by multinuclear NMR spectroscopy and mass spectrometry and the solid state structure of 1 was determined by single crystal X-ray diffraction. In the crystal of 1 a 1D zigzag polymeric chain was formed by Se•••Hg secondary interactions.
