Abstract
The title polymeric complex, [HgI2(C10H14N2)]n, was prepared from a solution of nicotine, mercury(II) iodide and 4-cyanopyridine in dimethylformamide. Each nicotine molecule 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 coordination around mercury is completed by two iodide ligands, resulting in a distorted tetrahedral arrangement.
