Dinitrogen reduction with diamagnetic trivalent lanthanum complexes is possible for the first time using a combination of a trivalent metallocene and potassium graphite. Both [(C 5 Me 4 H) 3 La] and [(C 5 Me 5 ) 2 La][BPh 4 ] are viable starting materials and reduce dinitrogen in the presence of KC 8 to give [NN] 2− containing structures (see picture).
