The origin of the hydrogenation of the dinitrogen ligand in [(η5-C5Me4H)2Zr]2(μ2,η2,η2-N2) has been investigated by a combined computational and experimental study. Density functional theory calculations on the zirconocenedinitrogencomplex demonstrate significant imido character in the zirconium nitrogen bonds, arising from effective π-back-bonding from the low-valent zirconium and the side-on bound
