Poly[(μ2-2-amino­pyrimidine-κ2 N 1:N 3)di-μ2-chlorido-mercury(II)]

The title compound, [HgCl 2 (C 4 H 5 N 3 )] n , features a two-dimensional network parallel to (001) that is based on an Hg II atom octahedrally coordinated by four μ 2 -Cl atoms and two μ 2 -2-amino­pyrimidine (apym) ligands in trans positions, yielding a distorted HgCl 4 N 2 octa­hedron. The coord...

Description
Summary:The title compound, [HgCl 2 (C 4 H 5 N 3 )] n , features a two-dimensional network parallel to (001) that is based on an Hg II atom octahedrally coordinated by four μ 2 -Cl atoms and two μ 2 -2-amino­pyrimidine (apym) ligands in trans positions, yielding a distorted HgCl 4 N 2 octa­hedron. The coordination network can be described as an uninodal 4-connected net with the sql topology. The Hg II ion lies on a site of -1 symmetry and the apym ligand lies on sites of m symmetry with the mirror plane perpendicular to the pyrimidine plane and passing through the NH 2 group N atom. This polymeric structure is stabilized by N—H⋯Cl hydrogen bonds and columnar π–π stacking of pyrimidine rings, with a centroid–centroid distance of 3.832 (2) Å.
