Catena-Poly[[dichloridomercury(II)]-?-{N-[(E)-pyridin-2-yl-methyl-idene-?N]pyridin-3-amine-?(2)N(1):N(3)}].


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 ?-? inter-actions between the pyridine rings, with a centroid-centroid separation of 3.529?(9)?Å.
