A new one-dimensional(1D) coordination polymer [Zn(MMTA)2]n(MMTA=5-mercapto-l-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, fl=120.84(3)^*, V=2.1243(2) nm^3, and Z=8. The deprotonated HMMTA molecule as a/a2-1igand links the zinc center, forming ID chains, which are luther 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 ℃.

With dimethylamine as a template, a new one-dimensional zincophosphite (C2H8N)·[Zn(HPO3)(H2PO3)] was prepared under hydrothermal conditions and characterized by single-crystal X-ray diffraction, FTIR spectrametry, elemental analysis, powder X-ray diffraction, and thermogravimetric analysis. The compound crystallized in the Monoclinic space group P2(1)/c, with cell parameters, a=0.78410(9) nm, b=1.54744(2) nm, c=0.81418(1) nm, β=105.8150(1)°, V=0.95049(2) nm3 and Z=4. The connectivity of the ZnO4 tetrahedron and HPO3 pseudo pyramid resulted in inifinite corner-sharing 4-membered ring chains, which were further linked by the protonated amine molecules to form a 3D structure via hydrogen bonds. To the best of our knowledge, this is the first existence of a zincophosphite with the anionic framework composition of [Zn(HPO3)(H2PO3)]-. The compound exhibits intense photoluminescence at room temperature.
