摘要：
The reactions of [NBu4](2)[ReX5(NO)] (X = Cl, Br) with triphenylstibine have been examined and three new rhenium complexes [ReCl2(NO)(SbPh3)(3)] (1), [ReBr2(NO)(SbPh3)(3)] (2) and [ReBr2Cl(SbPh3)(3)] (3) - have been obtained. The last one has been isolated in a low yield during slow recrystallization of the complex 2 from a mixture of chloroform and ethanol. The stibine rhenium nitrosyls have been characterized by IR and UV-vis spectroscopy. The X-ray structures of and 3 have been determined. The geometric parameters of 1 have been examined using the density functional theory (DFT) method. (C) 2005 Elsevier Ltd. All rights reserved.
