The title compound,poly[N-[1-(3-pydidyl)ethylidene]-4H-1,2,4-triazol-4-amine sil-ver(I) tetrafluoroborate],[Ag(C9H9N5)(BF4)]n,is the result of complexing Ag cation with N-[1-(3-pydidyl)ethylidene]-4H-1,2,4-triazol-4-amine (L),and its crystal structure was determined by single-crystal X-ray diffraction.The crystal belongs to the monoclinic system,space group C2/c with a= 18.899(6),b=9.882(2),c=15.472(4),β=120.158(3)°,V=2498.5(11)3,C9H9AgBF4N5,Mr= 381.89,Dc=2.031 g/cm3,μ(MoKα)=1.659 mm-1,F(000)=1488,Z=8,the final R=0.0441 and wR=0.0619 for 1094 observed reflections (I > 2σ(I)).In the structure,ligand L bridges the two metal Ag(I) centers in a bidentate fashion and each metal ion coordinates with two nitrogen atoms,forming a one-dimensional rectangular chain.The neighboring chains are connected by two additional Ag-N weak interactions into a 3D framework structure.The title compound shows blue fluorescence property at room temperature.
