摘要：

(Chemical Equation Presented) Low-spin, high-valent iron centers: A high-valent iron-nitrido species containing a Fev center is accessible by the photolysis of [(cyclam-ac) FeIIIN3] +. The identity of the resulting [(cyclam-ac)Fev(N)] + species was verified by spectroscopic methods, magnetic susceptibility data, and DFT calculations (see picture). Unexpectedly, the analysis provides strong evidence for a low-spin d3 (S = 1/2) ground-state electron configuration at the Fev center. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
