title: catena-Poly[[[dichloridomercury(II)]-μ-1,4-bis-(3-pyridyl-amino-meth-yl)benzene-κN:N'] N,N-dimethyl-formamide monosolvate].
abstract: The crystal structure of the polymeric title compound, {[HgCl(2)(C(18)H(18)N(4))]·C(3)H(7)NO}(n), features an N-heterocyclic ligand which links adjacent HgCl(2) units into a helical chain running along the b axis. The coordination geometry of the Hg(II) atom is a distorted tetra-hedron. The dimethyl-formamide mol-ecule is disordered over two positions in a 1:1 ratio, and is linked to the complex mol-ecules via N-H⋯O hydrogen bonds.
