Density functional calculations on the model compound [U2(µ2-N2)(¿5- C5H5) 2(¿8- C8H6)2] support the formulation of the recently characterized dinitrogen complex [U2(µ2- N2)(¿5-C5Me5)2 (¿8-C8H4(SiPri3) 2)2] as containing two U(IV) f2 centers bridged by a N22- ligand. The N-N distance found experimentally (1.232 Å) can be modeled only in a geometry optimization by a non-aufbau occupation of the orbitals. Though both N2 pg orbitals overlap significantly with U 5f orbitals, only the more stable of the two is occupied in the optimum calculation
