摘　　要：A silver(Ⅰ) complex has been obtained from reaction of silver salt and 4-Hpytz(4-Hpytz=3,5-di(4-pyridyl)-1,2,4-triazole) by hydrothermal method.Single crystal structure reveals that it consists of a 2D coordination polymer [Ag(4-pytz)]∞(1)(4-pytz=3,5-di(4-pyridyl)-1,2,4-triazolate),which was crystallized in monoclinic crystal system and space group of P21/c,with a=0.753 64(1) nm,b=1.135 55(2) nm,c=1.291 7(2) nm,β=104.015(4)°,V=1.072 5(3) nm3,Z=4.Each Ag(Ⅰ) ion has a trigonal coordination geometry which three N atoms from two bridging pytz ligands.4-pytz shows-1 valence which lost its proton located at a triazole ring in final product.The title complex exhibits high thermal stability and decomposed at 472 ℃.Furthermore,complex 1 shows obvious luminescence with λem at 547 nm,which is ascribed to MLCT.A silver（I） complex has been obtained from reaction of silver salt and 4-Hpytz（4-Hpytz=3,5-di（4-pyridyl）- 1,2,4-triazole） by hydrothermal method. Single crystal structure reveals that it consists of a 2D coordination polymer [Ag（4-pytz）]∞（1） （4-pytz=3,5-di（4-pyridyl）-1,2,4-triazolate）, which was crystallized in monoclinic crystal system and space group of P21/c, with a=0.753 64（1） nm, b=1.135 55（2） nm, c=1.291 7（2） nm, β=104.015（4）°, V=1.072 5（3） nm^3, Z=4. Each Ag（I） ion has a trigonal coordination geometry which three N atoms from two bridging pytz ligands. 4-pytz shows -1 valence which lost its proton located at a triazole ring in final product. The title complex exhibits high thermal stability and decomposed at 472℃. Furthermore, complex 1 shows obvious luminescence with λem at 547 nm, which is ascribed to MLCT. CCDC： 663937.
