Abstract

In the title coordination polymer, [HgCl(2)(C(11)H(9)N(3))](n), the Hg(II) ion is coordinated by three N atoms from two N-[(E)-pyridin-2-yl-methyl-idene]pyridin-3-amine (L) ligands and two chloride anions in a distorted trigonal-bipyramidal geometry. The two pyridine rings in L form a dihedral angle of 50.0 (2)°. L ligands bridge adjacent HgCl(2) units into polymeric chains propagating in [010]. The crystal packing is further stabilized by weak inter-molecular C-H⋯Cl hydrogen bonds and π-π inter-actions between the pyridine rings, with a centroid-centroid separation of 3.529 (9) Å.
