双乙酰丙酮和1，10-菲咯啉的双核钯(Ⅱ)配合物的合成与谱学研究

Synthesis and Spectroscopic Studies of Di-palladium(Ⅱ) Complex with Bisacetylacetonate and 1,10-Phenanthroline

以二氯化钯、1,10-菲咯啉(phen)、二乙酰丙酮为原料合成了钯(Ⅱ)的新型固态三元配合物[Pd2(C10H12O4)(C12H8N2)2](PF6)2,并用元素分析、电导率、红外光谱、紫外-可见光谱、核磁共振光谱、电喷雾质谱和荧光光谱对其进行了表征,确定了配合物的组成。结果表明:该配合物属于低自旋的平面正方形,并且由于配合物中离域π键和螯合环的形成,使Pd—O和Pd—N键得到加强,配合物较稳定。

The synthesis and spectroscopic properties of the novel dium（ Ⅱ ） complex, [Pd2（C10H12O4）（C12H8N2）2] （PF6）2 with bisacetylacetonate-bridged di-pallapalladium chloride, 1, 10-phenanthroline and bisacetylacetone were reported. The complex was identified and characterized by elemental analysis as well as by conductance and spectroscopic measurements （IR, UV- Vis, ^1H NMR, ESI MS）. The results showed that the complex was square planar with low spinning and that the Pd-O and Pd-N coordination bonds were strengthened due to the formation of conjugated π bonds. As a result the di-palladium（ Ⅱ ） complex was quite stable.
