A new two-dimensional coordination polymer of mercury(II) with very high thermal stability

摘要

A 2D Hg-II coordination polymer containing ligands 1.2,4-triazole (Htrz) and thiocyanate, [Hg(mu(3)-trz)(SCN)](n) (1) has been synthesized and characterized by elemental analysis and IR spectroscopy. The single-crystal X-ray data show the coordination number of Hg atoms is four and the ligand trz(-) acts as a threefold donor. The thermal stability of compound 1 was studied by thermal gravimetric and differential thermal analyses. The composition and formation of the complex in methanol solution were found to be in support of its solid state structure.
