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℃.

摘 要:本文通过对近年来汉语中的类比新词进行调查研究,发现由于类比词的大量繁衍产生了一系列的类词缀现象。与此同时,结合对类词缀产生的原因和途径进行的分析,我们认为类词缀构词在汉语构词法中发挥了越来越重要的作用。  关键词:类比词 类词缀 词缀化  中图分类号:G642.3 文献标识码:A文章编号:1673-1875(2008)03-057-02    一、引言    近年来,现代汉语词汇系统发生了
