| 摘要: 以3-甲基-4-乙基-5-（2-吡啶基）-1，2，4-三唑（L）和3-甲基-4-乙基-5-（4-吡啶基）-1，2，4-三唑（L'）为配体分别合成了2个银(Ⅰ)配合物[Ag2（μ-L）2L2（NO3）2]（1）和{[Ag2（μ-L'）2（H2O）2]（NO3）2}n（2），测定了X射线单晶结构，用红外光谱、荧光和热重等进行了表征。2个配合物都属于三斜晶系，空间群为P1。晶体结构分析表明2个配合物都具有畸变的四面体结构[AgN3O]。配合物1.是一个双核银(Ⅰ)配合物，NO3-参与配位；而配合物2是一个配位聚合物，水分子参与配位。 | |

| Abstract: Two Ag(Ⅰ) complexes of[Ag2(μ-L)2L2(NO3)2] (1) and {[Ag2(μ-L')2(H2O)2](NO3)2}n (2), where L (or L')=3-methyl-4-ethyl-5-(2(or 4)-pyridyl)-1,2,4-triazole, have been synthesized and characterized by single-crystal X-ray diffraction, IR, fluorescence measurement and TGA. Complexes 1 and 2 crystallize in triclinic system with space group P1. Crystallographic studies show that both complex 1 and 2 have a distorted tetrahedral core[AgN3O] with one NO3- in 1 but one coordinated H2O molecule in 2. Complex 1 is a binuclear silver(Ⅰ) complex bridged through the nitrogen atoms of triazole rings. Complex 2 is a polymer complex bridged by the nitrogen atoms of pyridine and triazole rings.
