title: catena-Poly[[diiodidomercury(II)]-μ-nicotine-κN:N'].
abstract: The title polymeric complex, [HgI(2)(C(10)H(14)N(2))](n), was prepared from a solution of nicotine, mercury(II) iodide and 4-cyano-pyridine in dimethyl-formamide. Each nicotine mol-ecule is bonded to two Hg atoms, one through the pyrrolidine N atom and the other through the pyridine N atom, forming infinite zigzag polymeric chains. The coordin-ation around mercury is completed by two iodide ligands, resulting in a distorted tetra-hedral arrangement.
