What is 2,2'-DIPYRIDYL N,N'-DIOXIDE?
Chemical properties
off-white to cream powder
General Description
Complexation abilities of 2,2′-dipyridyl N,N′-dioxide (2,2′-bipyridyl-N,N′-dioxide, bipyO2) as a ligand towards zinc has been compared with 2,2′-bipyridine. Novel lanthanide (Eu3+, Tb3+, Gd3+, Sm3+ and Dy3+) complexes of bipyO2 were synthesized and characterized by elemental analysis and IR spectrum. Electron density study of halogen-bonded complex of bipyO2 with 1,4-diiodotetrafluorobenzene (F4dIb) at 90K by X-ray diffraction has been reported.
