Abstract One-pot reaction of S2O2-macrocyclic ligand L with AgClO4 together with 4,4′-bipyridine (bpy) afforded a unique dumbbell-shaped complex 1, [(AgL)2(μ-bpy)](ClO4)2. The macrocyclic dinuclear silver(I) complex 1 was structurally characterized by X-ray crystallography and MALDI-TOF-MS spectrometry. The crystal structure of 1 shows the silver(I) in a distorted square pyramidal environment formed
摘要 S2O2-大环配体 L 与 Ag 以及 4,4'-联吡啶 (bpy) 的一锅反应得到了独特的哑铃形配合物 1,[(AgL)2(μ-bpy)](ClO4)2。通过 X 射线晶体学和 MALDI-TOF-MS 光谱法对大环双核银 (I) 配合物 1 进行了结构表征。1 的晶体结构显示了银(I)在扭曲的方形金字塔环境中,由来自 L 的两个硫和两个氧供体以及来自 bpy 的一个氮供体形成。比较NMR研究表明溶液中存在配合物1。

Assembly reactions of mercury(II) halides (Cl, Br, and I) with two O2S2 macrocycles (L(1) and L(2)) having different interdonor (S...S) distances were investigated, and four types of supramolecular complexes (1-4b) were obtained depending on the S...S distances as well as the size of the halide anions. Photoluminescence of these compounds was also studied.
