Catena-Poly[[diiodidomercury(II)]-μ(2)-2-amino-pyrazine-κN:N].

ABSTRACT: 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-amino-pyrazine ligands in a distorted HgI(2)N(2) tetra-hedral geometry. In the crystal, the 2-amino-pyrazine 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 inter-molecular N-H⋯I hydrogen bonds.
