previously reported to react with dinitrogen to give the bridging
dinuclear complex [(PCP)Ir]2(N2) (2), which was crystallographically characterized. We report that under N2 atmosphere
the only observable nitrogen complex in solution is actually
the terminal dinitrogen complex (PCP)Ir(N2). The mono- and
dinuclear species are in equilibrium; the dinuclear complex
more readily crystallizes from solution.
