rH2 (rac-BpZrH2). In the presence of dinitrogen, rac-BpZrH2 undergoes thermal reductive elimination of H2 and reaction with N2, yielding the dinitrogen complex BpZr(μ2,η2,η2-N2)ZrBp, for which the dinitrogen ligand is coordinated in a side-on fashion to both zirconiums with a N−N bond distance of 1.241(3) Å. The doubly [SiMe2]-bridged zirconium dimethyl complex (Me2Si)2(η5-C5H3)2}ZrMe2 (RpZrMe2) undergoes
