Smdt F, Lamarche VME, Clentsmith GKB, Cloke FGN, Tuczek F. Vibrational and electronic stmcture of the dinuclear bis(p-nitrido) vanadium(v) complex [V(N N" 2)(p-N)]2 spectroscopic properties of the M2(p-N)2 diamond core. Dalton Trans 2005 1052-1057. 

In other systems, N—cleavage gives bis(/i-nitrido)dimetal diamond cores as the products of N2 cleavage. A reduced niobium complex of calix[4]arene reduces N2 in the presence of sodium metal, and a number of intermediates can be isolated. A related tridentate aryloxide ligand also splits N2 to give a diamond core with lithium ions bound to the nitrides. A vanadium diamidoamine complex reacts with N2 to give a product with a similar core structure, which may be further reduced by potassium graphite to a compound with one unpaired electron. This...
