摘要：

Localization versus delocalization: in the binuclear asymmetric Mo complex 1, a facile one-electron reduction with cobaltocene is sufficient to convert a system with localized electrons to one with delocalized electrons. Whereas according to the EPR spectrum the unpaired electron in the 17e, 16e complex 1 is localized at the Mo center coordinated to n, in the 17e, 17e diradical 1, a rapid site exchange of the two unpaired electrons occurs for which a rate of 4 x 10(7) Hz was determined. L* = hydro-tris(3,5-dimethylpyrazolyl)borate.
