摘　　要：以氯亚铂酸钾和自合成的5,10,15,20-四(4-羧基苯基)卟啉为原料合成了铂(Ⅱ)配合物。采用元素分析、电导测定、紫外-可见光谱、红外光谱、核磁共振和电喷雾质谱等多种物理手段表征了钯配合物的结构,对配合物的空间构型和成键性质进行了讨论。研究了配合物在氮气气氛中的热分解行为。结果表明:该配合物属于低自旋的平面正方形,配合物中离域π键和螯合环的形成使Pt-N键加强,配合物很稳定。In this paper, ligand of meso -tetra （4 -earboxyphenyl） porphyrin has been synthesized, and platinum （Ⅱ） complex was obtained by the reaction of the ligand and platinous potassium chloride. Molecular structures of the synthesized compound was confirmed by elemental analysis, conductivity measurement, UV - Vis spectra, IR spectra, 1H NMR spectra and ESI - MS. The configuration and bonding character of complex were discussed. Thermogravimetry （TG） and differential scanning calorimetry （DSC） for complex in an atmosphere of N2 were performed. In the chelating ring, conjugate π bonds were formed, which further strengthen the Pt - N co- ordination bonds and made Pt （Ⅱ） complex a stable compound.
