摘要具有邻甲氧基取代基的芳族叔膦配体与6族金属羰基反应形成配合物,并通过磷原子进行单齿键合。还形成了具有两个P键合的膦配体的一种六羰基钨衍生物。通过X射线晶体学,1 H,13 C {1 H}和31 P {1 H)NMR光谱,IR光谱和元素分析来表征配合物。通过分子建模方法研究了配体的空间性质。金属-磷键的距离与膦的锥角相关。

In the title compounds, [Cr(C21H21O3P)(CO)(5)] and [Mo(C-21 H21O3P)(CO)(5)], the M-C bend lengths for the cis-carbonyl ligands (with respect to the phosphine) are longer than that observed for the trans-carbonyl group. The chromium compound has short intermolecular O ... O contacts, The two crystal structures are not isomorphous and crystallize in triclinic and monoclinic systems, respectively.
