Proton, carbon-13, and nitrogen-15 nuclear magnetic resonance studies of a dinitrogen complex of permethyltitanocene. Evidence for molecular nitrogen coordinated edge-on to a transition metal

In connection with the current interest in transition metal dinitrogen complexes and their possible roles in nitrogen-fixing reaction systems, we have obtained results which bear on the structure of a titanium dinitrogen in solution. We report here successful application of ^(15)N nmr spectroscopy to studies of a transition metal dinitrogen complex which provides a potentially powerful technique for elucidation of the structure of such complexes.
