Fig. 5. a) Decomposition of (tBuPBP)Ni(CH3) under N2 at 60 °C. (b) Solid-state structure of (tBuPBMeP)2Ni2(μ-N2) with thermal ellipsoids at 30% probability. The model is near the crystallographic inversion center; half of the structure is generated by symmetry. Hydrogen atoms are omitted for clarity. Selected distances (Å) and angles (°): Ni(1)–N(1) 1.854(4), Ni(1)–P(1) 2.293(11), Ni(1)–P(2) 2.164(11), N(1)–N(1A) 1.145(8), P(1)–Ni(1)–P(2) 122.0(5), N(1)–Ni(1)–P(1) 118.9, N(1)–Ni(1)–P(2) 110.8(3), Ni(1)–N(1)–N(1A) 178.7(5).
