Abstract

The title compound, [HgI2(C10H8N2O2)], is a further example of a mercury halide complex of the chelating BipyO2 ligand (BipyO2 is 2,2′-bipyridine N,N′-dioxide). As observed for similar compounds, the coordination polyhedron of the Hg atom is a severely distorted tetrahedron, in which Hg is coordinated by two I atoms and two O atoms of the ligand.

Abstract

In the crystal structure of the title compound, [HgCl2(C10H8N2O2)], the Hg atom has severely distorted tetrahedral coordination by two Cl atoms and by two O atoms of the chelating ligand. Additional weak Hg⋯Cl bonds link the mol­ecules into a chain.
