摘 要: 根据金属与卟啉的配位模式及金属离子的性质,建立了一个用以判断金属卟啉热力学稳定性大小的经验关系式: S_M=[0.18×(1.34)^(2-Z)]ZE_B/(|R-r_M|^(1/2)) 利用上式计算了48个常见金属卟啉配合物的隐定系数S_M,计算结果与实验观察的金属卟啉的稳定性顺序和稳定性级别基本一致。 A correlative formula deseribing the thermodynamic stability of metalloporphrins has been developed on the basis of the propcrics of metalions and the coordination types of metalions with porphyrin: S_M=[0.18×(1.34)^(2-Z)] ZE_B/|R-r_M|1/2 By this formula the stability indexes (S_M) for 48 metalloporphyrins have been calculated.The results coincide with the observed stability order and classes of metalloporphyrins.
