Crystal structure of an Hg^II coordination polymer with an unsymmetrical dipyridyl ligand: catena-poly[[[di-chlorido-mercury(II)]-μ-N-(pyridin-4-ylmeth-yl)pyridin-3-amine-κ²N:N'] chloro-form hemisolvate].

ABSTRACT: The asymmetric unit of the title compound, {[HgLCl₂]·0.5CHCl₃} _n (L = N-(pyridin-4-ylmeth-yl)pyridin-3-amine, C₁₁H₁₁N₃), contains one Hg^II ion, one bridging L ligand, two chloride ligands and a chloro-form solvent mol-ecule with half-occupancy that is disordered about a crystallographic twofold rotation axis. Each Hg^II ion is coordinated by two pyridine N atoms from two symmetry-related L ligands and two chloride anions in a highly distorted tetra-hedral geometry with bond angles falling in the range 99.05 (17)-142.96 (7)°. Each L ligand bridges two Hg^II ions, forming polymeric zigzag chains propagating in [010]. In the crystal, the chains are
