摘要：

The reaction of chromium(III) chloride, 3-hydroxy-2-naphthoic acid (3-HNA) and ethylenediamine (en) led to the formation of complex [Cr(3-HNA)(en)(2)]Cl (.) H2O (.) CH3OH, Bis(ethylenediamine-kappa N-2,N')(3-hydroxy-2-naphthoic acid-kappa O-2,O,) chromium(III) monochloride monohydrate monomethanol. The kinetics of transfer of Cr(III) from the title compound to the low-molecular-mass chelator EDTA and to the iron-binding protein apoovotransferrin (apoOTf) were carried out by means of UV-Visible (UV-Vis) and fluorescence spectra in 0.01 M Hepes at pH 7.4. The second-order rate constants were calculated, respectively. The results show that Cr(III) can be transferred from the complex to apoovotransferrin. (c) 2006 Elsevier B.V. All rights reserved.
