synthesized by the reaction of AgNO3 with 3-(5-furyl-1,3,4-oxadiazol-2-yl)acrylic acid (HL, C9H6N2O4), and its crystal structure is determined (CIF file CCDC no. 1426528). The crystals are monoclinic, space group P21/n, a = 4.946(1), b = 20.084(1), c = 9.015(1) Å, β = 92.32(1)°, V = 894.482 Å3, ρcalcd = 2.442 g/cm3, Z = 4. In structure I, pairs of centrosymmetric silver atoms are bound by bidentate-bridging
金属配合物[AgL](I)通过AgNO 3与3-(5-呋喃基-1,3,4-恶二唑-2-基)丙烯酸(HL,C 9 H 6 N 2 O 4)反应合成,并确定其晶体结构(CIF文件CCDC号1426528)。该晶体是单斜晶系,空间群P 2 1 / Ñ,一个= 4.946(1),b = 20.084(1),C ^ = 9.015(1),β= 92.32(1)°,V = 894.482埃3,ρ计算为2.442 g / cm3,Z =4。在结构I中一对中心对称的银原子被两个阴离子L的二齿桥接氧原子束缚成二聚体嵌段。二聚体中的Ag–Ag距离为2.854(1)Å。Ag +的配位球包含两个氧原子,一个银原子和一个相邻阴离子的重氮基片段的氮原子。Ag +的配位多面体是强烈变形的四面体。晶体I的分子堆积由沿[001]方向延伸的无限带(AgL)n构成。化合物I的光致发光光谱包含对应于绿色光谱范围的约550nm的强
