- Title
Synthesis and structure of a (NacNac)rhodium terminal dinitrogen complex.

- Abstract
Reaction of the ligand salt CH[C(Me)(N-i-Pr2C6H3)]2Li(Et2O) with [Rh(COE)(µ-Cl)]2 proceeds to give the brown crystalline product CH[C(Me)(N-i-Pr2C6H3)]2Rh(N2)(COE) (1) in 38% yield. X-ray crystallographic study of 1 confirmed the formulation and revealed that the terminally bound dinitrogen molecule exhibits a Rh—N distance of 1.943(4) Å and an N—N distance of 1.091(6) Å. Comparison to other Rh–N2 complexes shows that the N—N distances reflect a complex admixture of the trans influence and the net electron density at the metal center.Key words: rhodium, dinitrogen, diimine, structure.
