| Abstract: | The reaction of the reactive clathrochelate FeBd2(Cl2Gm)(BF)2 (Bd and Cl2Gm are the α -benzyl dioxime and dichloroglyoxime dianions, respectively) with amino-substituted nitroxide TEMPO-NH2 afforded new mono- and biradical iron(II) mono- and dinitroxide clathrochelate complexes. The complexes were characterized by X-ray diffraction and spectroscopic (UV-Vis, ESR, and 57Fe Mossbauer) methods. Dedicated to Academician N. K. Kochetkov on the occasion of his 90th birthday. __________ Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 5, pp. 1097–1102, May, 2005. |
