چکیده
In the title coordination polymer, [Hg₄Cl₄(C₂₆H₂₀N₆)](n), one Hg(II) ion is coordinated by four N atoms from the benzylbis((pyridin-2-yl)methyl-idenehydrazone) ligand and two Cl⁻ ions in a very distorted cis-HgCl₂N₄ octa-hedral geometry. The other Hg(II) ion is coordinated in a distorted tetra-hedral geometry by four Cl⁻ ions. Bridging chloride ions link the Hg(II) ions into a chain propagating in [010]: the Hg-Cl bridging bonds are significantly longer than the terminal bonds. The dihedral angle between the central benzene rings of the ligand is 83.3 (2)°. The packing is consolidated by weak C-H⋯Cl hydrogen bonds and C-H⋯π inter-actions.

The crystal structure of the title complex, {(C(2)H(8)N)[CuCl(2)(N(3))]}(n), exhibits inorganic chains consisting of Cu(II) cations as well azide and chloride anions. The chains, made up from Cu-Cl-Cu-N-Cu linkages, are aligned parallel to the c axis. This architecture is further stabilized by a number of N-H⋯Cl hydrogen bonds involving the protonated charge-compensating dimethyl-amine cations ...
