摘要：

The reaction of [WI2(CO)(3)(NCMe)(2)] with two equivalents of PEt3 in Et2O/CH2Cl2 gives the MeCN-displaced product [WI2(CO)(3)(PEt3)(2)] (1) in high yield. The crystallographically determined solid state structure of (1) shows the complex to be capped octahedral with a carbonyl ligand capping an octahedral face containing the two octahedral carbonyls and one PEt3 group. The other face contains the two iodo ligands trans to carbonyl groups, and the second PEt3 ligand trans to the first PEt3 group. The low temperature (-30 degrees C) C-13-{H-1}-n.m.r. spectrum of (1) correlates with the solid state structure, and the fluxional properties of (1) have been investigated by VT P-31-{H-1}-n.m.r. spectroscopy.
