摘　　要：以配体3-((5-(3-吡啶基)-2-(1,3,4-噁二唑基))硫代)-2,4-戊二酮(L_(1))与AgSbF_(6)进行配位反应,得到配位聚合物{[Ag(L_(1))2]SbF_(6)}_(n)(1);以配体3-((5-(4-吡啶基)-2-(1,3,4-噁二唑基))硫代)-2,4-戊二酮(L_(2))与AgCF_(3)SO_(3)进行配位反应,得到配位聚合物[Ag(L_(2))(CF_(3)SO_(3))]n(2)。并通过粉末X射线衍射、红外光谱、元素分析和单晶X射线衍射对配合物的结构进行了表征。在固体状态下,配位聚合物1和2都形成1D链状结构。We performed a coordination reaction between ligand 3-(5-(3-pyridyl)-2-(1,3,4-oxadiazoles))thio)-2,4-glutaric ketone(L1)and AgSbF6 to obtain a coordination polymer{[Ag(L_(1))_(2)]SbF_(6)}_(n)(1).The ligand 3-((5-(4-pyridyl)-2-(1,3,4-oxadiazole))thio-2,4-pentanedione(L_(2))was used to react with AgCF_(3)SO_(3)to obtain a coordination polymer[Ag(L2)(CF_(3)SO_(3))]n(2).The structures of the two complexes were characterized by powder X-ray diffraction,infrared spectroscopy,elemental analysis,and single-crystal X-ray diffraction.In the solid state,coordination polymers 1 and 2 form 1D chain structures,and the coordination configuration of Agions is a twisted tetrahedron.The carbonyl oxygen atoms of theβ-diketone units in the two complexes do not coordinate with Ag(Ⅰ)ions,providing the possibility for constructing heteronuclear complexes.CCDC:2283712,L2;2283714,1;2283713,2.
