文摘

Synchrotron-based X-ray photoelectron spectroscopy is used tomeasure N 1s binding energies of several metal amido, imido,and nitrido complexes of group 5 and 6 metals. The N 1s bindingenergy decreases as the formal M-N bond order increases. Asimple correlation between the contraction of the M-N bond andthe lowering of binding energy is also observed. This correlationsupports a notion that the bonding character of a linear metal-imido linkage resembles that of a metal-nitrido linkage closely.
