摘　　要：The title complex {[AgL]ClO4}n（L=2,5-bis（3-pyridinylmethylthio）-1,3,4-thiadiazole） was synthesized by the reaction of Ag（I） salt and a novel flexible ligand L.Its structure was determined by X-ray crystallography with the following data：monoclinic,space group P21/n,a=16.5068（13）,b=7.6548（4）,c=16.5521（13）A,β=115.119（3）o,V=1893.7（2）A^3,Z=4,Dc=1.893 g/cm^3,μ=1.565 mm^-1,F（000）=1072,C14H12AgClN4O4S3,Mr=539.78,T=293（2） K,S=1.067,the final R=0.0342 and wR=0.0870.The silver ion in the complex is in a trigonal coordination geometry to link three different L.Meanwhile,each L connects three different silver ions by its N coordination sites to form a two-dimensional layer structure.The title complex {[AgL]ClO4}n（L=2,5-bis（3-pyridinylmethylthio）-1,3,4-thiadiazole） was synthesized by the reaction of Ag（I） salt and a novel flexible ligand L.Its structure was determined by X-ray crystallography with the following data：monoclinic,space group P21/n,a=16.5068（13）,b=7.6548（4）,c=16.5521（13）A,β=115.119（3）o,V=1893.7（2）A^3,Z=4,Dc=1.893 g/cm^3,μ=1.565 mm^-1,F（000）=1072,C14H12AgClN4O4S3,Mr=539.78,T=293（2） K,S=1.067,the final R=0.0342 and wR=0.0870.The silver ion in the complex is in a trigonal coordination geometry to link three different L.Meanwhile,each L connects three different silver ions by its N coordination sites to form a two-dimensional layer structure.
