Summary:In the crystal of the title polymeric compound, [HgI 2 (C 4 H 5 N 3 )] n , the Hg II cation is located on a twofold rotation axis and is coordinated by two I − anions and two 2-amino­pyrazine ligands in a distorted HgI 2 N 2 tetra­hedral geometry. In the crystal, the 2-amino­pyrazine ligand is equally disordered over two positions about an inversion center, and bridges the Hg II cations with pyrazine N atoms to form a polymeric chain running along the c axis. In the polymeric chain, the amino groups link to the coordinated I − anions via inter­molecular N—H⋯I hydrogen bonds.
