Infrared spectra of complexes of Rh(I), Ir(I), Ru(II), and Os(II), containing molecular nitrogen

Ammine Complexes of Osnium(II)

“…By contrast, the [Os(NH3),(N2)I2+ ion exhibits a moderate intensity band at 499-524cm-' assigned by Borod'ko et al (17) to v(0s-N,), but by comparison with carbonyl and nitrosyl complexes, more likely to be G (Os-N-N).…”
