A reaction of Pd(PPh3)4 (complex 1) and 2-chloroquinoline C9H6NCl in a 1:1 molar ratio produces a mononuclear [Pd(PPh3)2{κ1-C9H6NB}(Cl)] complex (complex 2) and a binuclear [Pd(PPh3)2Cl]2{μ,κ2-C9H6N} complex (complex 3). In complex 3, each of quinoline units is bridged through the carbon atom of quinoline groups to one metal center and the nitrogen atom to another metal, forming a six-membered ring with the boat-like geometry. Complexes 2 and 3 are characterized by the elemental analysis, fast atom bombardment mass spectrometry, 31P NMR spectroscopy, and single crystal X-ray diffraction.

喹啉基钯 (II) 配合物的晶体结构:[Pd(PPh3)2{κ1-C9H6NB}(Cl)] 和 [Pd(PPh3)2Cl]2{μ,κ2-C9H6N}

Pd(PPh3)4(复合物 1)和 2-氯喹啉 C9H6NCl 以 1:1 的摩尔比反应生成单核 [Pd(PPh3)2{κ1-C9H6NB}(Cl)] 复合物(复合物 2)和双核[Pd(PPh3)2Cl]2{μ,κ2-C9H6N} 复合物(复合物 3)。在配合物3中,每个喹啉单元通过喹啉基团的碳原子桥接到一个金属中心,氮原子桥接到另一种金属,形成具有船形几何形状的六元环。配合物2和3的特征是元素分析、快速原子轰击质谱、31P核磁共振谱和单晶X射线衍射。
