摘要
合成了银(Ⅰ)的3,6-二(2-吡啶巯基)哒嗪配合物,{[Ag2(C14H10N4S2)3]n.4.5nH2O.2nNO3-}(1),通过红外光谱、元素分析和单晶X射线分析技术给予表征。配合物1是具有(6,3)拓扑的二维蜂窝网状结构的配位聚合物,银(I)中心为三角平面配位几何构型。晶体结构为三角晶系,R-3:空间群,a=15.555(3),b=15.555(3),c=42.587(8),α=β=90°,γ=120°,Z=6,V=892 4(3)3,R1=0.064 5,wR2=0.213 3。二维网状结构沿着c轴准确堆积为具有一维通道的(6,3)拓扑蜂窝层。配合物1的循环伏安测定表明电极反应是准可逆反应。
Silver(Ⅰ) complex with 3,6-bis(2-pyridylthio)pyridazine,{[Ag2(C14H10N4S2)3]n.4.5nH2O.2nNO3}(1),has been prepared and characterized by IR,elemental analysis and single-crystal X-ray diffraction analysis.Complex 1 is a novel two-dimensional honeycomb-like network coordination polymer with(6,3) topology,and the silver(I) centres exhibit trigonal coordination geometry.It crystallized in Trigonal,space group R-3,with a =15.555(3),b =15.555(3),c=42.587(8) ,α=β=90°,γ=120°,Z=6,V=892 4(3)3,R 1 =0.064 5 and wR 2 =0.213 3.The 2-D layers stack to form honeycomb-like 1-D channels along c-axis.The cyclic voltammetry measuring of complex 1 shows that the redox couple is quasi-reversible redox reaction.
