The reaction of N-(2-pyridyl)carbonylaniline (L) with Zn(NO 3)2, CdCl2, and Hg(SCN)2 gives the following complexes: [Zn(L)2](NO3)2, [Cd(L)2Cl2], and [Hg(L)(SCN)2]. The new complexes were characterized by elemental analyses and IR-, 1H-, 13C-NMR spectroscopy. The crystal structure of the [Hg(L)(SCN) 2] was determined by single crystal X-ray analysis. The monomeric complex is built up of a Hg(SCN)2 unit with one N-(2-pyridyl) carbonylaniline (L) ligand coordinated to the Hg atom via the ring pyridinic nitrogen atom and the carbonyl oxygen atom forming a five-membered chelate ring. The Hg atom has a distorted tetrahedral environment. There is π-π stacking interaction between the parallel aromatic rings belonging to adjacent chain as planar species in which the mean molecular planes are close to parallel and separated by a distance of ～ 3.5 A, close to that of the planes in graphite. The coordinated N-(2-pyridyl)carbonylaniline (L) molecule is involved in hydrogen bonding acting as hydrogen-bond donors with S and N atoms from SCN- ligand as potential hydrogen-bond acceptors. There is a shortest intermolecular contacts between the S and N atoms. The hydrogen bonding and shortest intermolecular contacts between the S and N atoms yields infinite chains parallel to the crystallographic vector c. Each molecule is bonded to two neighbors.
