摘要: 本文考察了六种酸性磷(膦)酸酯铜(Ⅱ)配合物的室温固态ESR波谱, 并测得它们在四氢呋喃中在低温下ESR波谱参数, 计算了这类配合物的键参数和约化能级差, 讨论了它们的成键特性, 指出: 这类配合物中平面内σ-配键是起主要作用的, 而平面内的π-配键的成键作用也不能忽视。

Abstract: In the present paper ESR spectra of six acidic phosphates (phosphonates) co- pper (Ⅱ) complexes in solid state at room temperature have been examined, and their ESP spectral parameters in THE at low temperature have been determined. The bonding parameters and difference of reducible level of these complexes were calculated. The bonding characterization of these copper (Ⅱ) complexes were dis- cussed. The result shows that the in-plane σ-bond in these complexes plays an important role, but the action of in-plane π-bond on bonding of these complexes may not be also neglected.
