十二氢十二硼酸双桥氯四(三苯基膦)合双钯(Ⅱ)的拉曼光谱和红外光谱

Infrared and Raman Spectra of [Pd_2Cl_2(PPh_3)_4] · B_12H_12

十二氢十二硼酸双桥氯四(三苯基膦)合双钯(Ⅱ)是一种新合成的红色粉末状固体,其元素分析测定值与理论值相符,但其拉曼光谱与红外光谱尚未见报道.为了探讨这类配合物的分子结构,我们参照有关文献,测定了它们的拉曼光谱和红外光谱,并对其特征频率进行了初步的归属和指认.

The IR and Raman spectra of PdCl2(PPh3)2 and [Pd2Cl2(PPh3)4] ·B12H12 were determined. Based on the observed Raman frequencies, the Pd-Cl stretching vibration can be assigned at 311-312 cm-1(one band) for [Pd2Cl2(PPh3)4] · Bi2H12. Similarly, the Pd-P stretching bands are assigned at 153-156 cm-1 and at 147 cm-1 for [Pd2Cl2(PPh3)4] ·B12H12.
