Synthesis and Characterization of a One-dimensional Coordination Polymer Generated from Unsymmetrical Bridging Organosulfur Ligand


  A new one-dimensional(1D) coordination polymer [Zn(MMTA)2]n(MMTA=5-mercapto-1-methyl-tetrazole) was synthesized under solvothermal conditions and characterized by single crystal X-ray diffraction. This compound crystallizes in the monoclinic space group C2/c,with cell parameters: a=1.4938(7) nm,b=1.3599(5) nm,c=1.2180(4) nm,β=120.84(3)°,V=2.1243(2) nm3,and Z=8. The deprotonated HMMTA molecule as a μ2-ligand links the zinc center,forming 1D chains,which are futher linked by weak C―H···N hydrogen bonds,forming a three-dimensional supramolecular framework. The compound exhibits intense photoluminescence at room temperature. On the basis of the results of TG/DTA analyses,the structure is thermally stable up to~280℃.……
