2,6-Bis(5,6-dipyridyl-1,2,4-triazinyl)pyridine (PyBTP) is an interesting ligand owing to the possible variation of itscoordinationsites and denticity in complexation. Therefore, solution and solid-phase lanthanide complexations were studied with PyBTP in two solvents, viz., acetonitrile and methanol, through various spectroscopic and single-crystal X-ray diffraction techniques. The results from all
2,6-Bis(5,6-dipyridyl-1,2,4-triazinyl)pyridine (PyBTP) 是一种有趣的配体,因为其配位位点和络合中的齿数可能会发生变化。因此,通过各种光谱和单晶 X 射线衍射技术,在两种溶剂(即乙腈和甲醇)中研究了溶液和固相镧系元素络合物与 PyBTP。所有这些研究的结果一致显示了对配体配位模式和齿数的溶剂依赖性变化的有趣观察,这是首次报道了三价镧系元素 (Ln3+) 配合物。配体配位受镧系离子大小的影响。
