S 89 Structural and physicochemical characteristics of chelate nickel(II ) compounds based on 1,2,3-triketone (hydrazone)imines [Electronic resource] / O. G. Khudina, E. V. Shchegol'kov, Ya. V. Burgart, V. I. Saloutin, O. N. Chupakhin // Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 2007. - Vol. 56, № 1. - P108-114 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: The crystal structures of the chelates NiIIL (L2? are the N,N?-(o-phenylene)-bis[4-(4-methylphenyl)hydrazono-3-oxo-1,1,2,2-tetrafluorononane-5-iminate], N,N?-ethylene-bis[3-(4-methylphenyl)hydrazono-4-oxo-5,5,6,6,7,7,8,8-octafluorooctane-2-iminate], or N,N?-ethylene-bis(4-hydroxy-5,5,6,6,7,7,8,8-octafluoro-3-octene-2-iminate) anions) were studied by X-ray diffraction. Magnetic measurements and ESR spectroscopic studies revealed the appearance of paramagnetism due to a tetrahedral distortion of the coordination unit and also the unusual behavior of the effective magnetic moment at low temperatures \\\\Expert2\\nbo\\Russian Chemical Bulletin\\2007, 56 (1), 108-114.pdf |
