摘要：

The diglyme complexes [MO2Cl2(C6H14O3)] (M = Mo or W) have been prepared by reaction of MoO2Cl2 or WOCl4-Me3SiOSiMe3 with diglyme. X-Ray diffraction studies have shown that in these complexes the metals exhibit distorted-octahedral geometry, with cis-dioxo and trans-chloro ligands. Two ether oxygen atoms are co-ordinated trans to the oxo ligands leaving one terminal oxygen atom of the ligand uncomplexed. Assignments of metal-ligand stretching vibrations as observed by IR and Raman spectroscopy are presented. Variable temperature C-13-{H-1} NMR spectra in CD2Cl2 solution indicate rapid intramolecular exchange between free and bound terminal oxygen atoms.
