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)-l,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. CCDC: 663937.
