Diiodo{N,N'-Bis(2,3,4-Trimethoxybenzaldehyde)-Ethylenediimine}Mercury(II): Synthesis and Crystal Structure1

摘要

Mononuclear mercury(II) complex [Hg((2,3,4-MeO-Ba)2En)I2] (I), where (2,3,4-MeO-Ba)2En = 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 C2/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)2En acts as a chelating ligand and coordinates via two N atoms to the mercury center and adopts an (E,E) conformation.
