摘要：
Mechanism of dinitrogen reduction in protic media is discussed in the light of results obtained for specially prepared binuclear complexes MNNM with bridging dinitrogen capable to be protonated and reduced. The conclusion is made that such complexes with d2 or d3 electronic configuration of M together with additional electron donor are likely intermediates in catalytic dinitrogen reduction by comparatively weak reducing agents. Model systems are compared with the active center of dinitrogen fixing enzyme, nitrogenase.
