Diiodo{N,N′-Bis(2,3,4-trimethoxybenzaldehyde)-ethylenediimine}mercury(II): Synthesis and crystal structure

Mononuclear mercury(II) complex [Hg((2,3,4-MeO-Ba) 2 En)I 2 ] ( I ), where (2,3,4-MeO-Ba) 2 En = N,N′-bis(2,3,4-trimethoxybenzaldehyde)ethylenediimine, has been synthesized and characterized by elemental analysis (C, H, and N) and confirmed by single-crystal X-ray diffraction analysis. The complex I crystallizes in the monoclinic system, with space group C 2/ c , having one symmetry-independent Hg 2+ ion coordinated in distorted tetrahedral geometry by two N atoms of the Schiff base ligand and by two I atoms. The Schiff base ligand (2,3,4-MeO-Ba) 2 En acts as a chelating ligand and coordinates via two N atoms to the mercury center and adopts an ( E,E ) conformation.
