Tripodal 1,2,3-triazole click ligand based on the triphenylphosphine oxide platform: atrane-type lanthanide complexes in solutions

摘要

phosphine oxide, a novel tripodal polytopic ligand produces stable complexes with La(NO3)3 and Lu(NO3)3. According to IR, multinuclear NMR and DFT data, the complexes have atrane-type structure with tetradentate O,N,N,N-coordination of ligand in MeCN solutions. Tris[2-(1-phenyl-1,2,3-triazol-4-ylmethoxy)phenyl]-
