Poly[mercury(II)-di--chloro--pyrazine-²N:N']

P. Nockemann and G. Meyer

Abstract: In [HgCl₂(Pyp)]_n (Pyp = pyrazine, C₄H₄N₂), chloride-bridged HgCl_4/2 strands are connected into layers by pyrazine molecules. The Hg atom is on a site of symmetry 2/m, the unique Cl atom is on a mirror plane, the unique N atom is on a twofold rotation axis, and the unique C and H atoms are in general positions.
