Synthesis and X-ray crystal structure of a complex formed by reaction of 1,2-bis(2'-pyridylethynyl)benzene and mercury(II) chloride
The X-ray crystal structure of the complex formed between 1,2-bis(2'-pyridylethynyl) benzene and mercuric(II) chloride is described. The complex (C40H24Cl6Hg3N4) crystallized in the triclinic space group P-1 with a=9.0414(6), b=9.4631(7), c=12.1134(9) Å, α=97.4680(10), β=94.8130(10), γ=105.4700(10)°. The structure reveals that the ligand is distorted from planarity to accommodate the mercury cation and a third mercuric chloride moiety is held between two ligand-mercury coordination complexes. The central mercury cation has octahedral coordination geometry surrounded by six chlorides while the other two mercury cations have distorted tetrahedral geometry each coordinated by two pyridyl nitrogen atoms and two chlorides.
