摘要
A mercury coordination polymer [Hg3（TizT）216]n （Mr = 1921.72, TizT = 2,4,6- tri（imidazole- 1-yl）- 1,3,5-triazine） containing a 40-membered macrocycle which was constructed by four TizT ligands and four mercury（II） iodide molecules had been synthesized by the reaction of HgI2 with TizT. The complex was characterized by elemental analysis, FT-IR, ^1H NMR spectra and X-ray crystallography. The crystal of the complex belongs to the monoclinic system and C2/c space group with a = 35.840（5）, b = 8.169（5）, c = 14.980（5） A, β = 104.466（5）°, Z= 4, V= 4247（3） A^3, De = 3.006 g·cm^-3, μ= 15.223 mm^-1, F（000） = 3384, Rint = 0.0504, wR = 0.0833 and constructs a chair-like conformation of cyclohexane one by one, which forms a 1-D polymer through the fashion of fused ring aromatic hydrocarbon. The hydrogen bonds and π-π interactions shape the 2-D network structure. The two compounds excited weak fluorescence.
