摘要：

The Grignard compounds MeMgBr and EtMgBr in n-Bu(2)O were studied at room temperature and -85 degrees C by extended X-ray absorption fine structure (EXAFS) spectroscopy above the magnesium and bromine K edges. The magnesium EXAFS studies were performed in the fluorescence mode with an UHV compatible cell for liquid samples. At both temperatures, dimers of the Grignard compounds are observed. By a combined analysis of the magnesium and bromine EXAFS spectra, the structure of the dimers of the Grignard compounds is deduced. Copyright (C) 1996 Elsevier Science Ltd
