Abstract: 1HNMR spectra of 2, 6-bis(benzoimidazal-2'-yl)pyridine and its Ru(I) complex were assigned by HOMO decoupling method. For the complex, H1, H2and H2' have a small downfield shift in comparison with the free ligand because of theσ-effect, while H9, H9' have a larger upfield shift because of the ring current effect of the phenyl groups.

Key words: 1H NMR, Spin-spin Decoupling, 2,6-Bis (benzoimidazol-2'-yl) pyridine/Ru (Ⅱ) complex
