Аннотация
Abstract The new ligand‐deficient chain polymer [Hg(μ‐Br) 2 (3,5‐Br 2 py)] ∞ has been obtained in form of single crystals by thermolysis of the ligand‐rich [Hg(μ‐Br) 2 (3,5‐Br 2 py) 2 ] ∞ at 180 °C at ambient pressure. From this reaction, high quality crystals of the product are directly accessible. The title compound features Hg II cations in a distorted square‐pyramidal coordination; their metal centers aggregate via edge‐sharing with asymmetric halide bridges to chains in which all apical N donor ligands are oriented to the same side of the [Hg(μ‐Br) 2 ] ∞ backbone. The new polymer cannot be prepared by stoichiometric reaction in solution.
