Synthesis and characterization of a one-dimensional coordination polymer generated from unsymmetrical bridging organosulfur ligand

A new one-dimensional(1D) coordination polymer [Zn(MMFA)(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, beta=120.84(3)degrees, V=2.1243(2) nm(3), and Z=8. The deprotonated HMMTA molecule as a mu(2)-ligand links the zinc center, forming ID chains, which are futher linked by weak C-H center dot center dot center dot N hydrogen bonds, forming a three-dimensional supramolecular framework. The compound exhibits intense photo luminescence at room temperature. On the basis of the results of TG/DTA analyses, the structure is thermally stable up to similar to 280 degrees C.
