| 摘 要： | 本文用1H、31P和13C核磁共振谱研究了ATMP(氨基三甲叉膦酸,以简式H6L表示)及其顺磁性Co(Ⅱ)配合物。测定了不同Cco/CATMP摩尔比在不同pH值下的各向同性位移。定性地讨论顺磁性Co(Ⅱ)配合物在不同pH条件下的组成、电荷和空间构型变化对化学位移的影响。运用快速交换反应中化学位移与配合物浓度的关系,确定不同pH下的条件稳定常数。

| Abstract: | The 1H,31P and 13C NMR spectra of ATMP and paramagnetic Co(II)-ATMP complexes have been studied. The isotropic shifts under different Cco/CATMP molar ratios at different pH values have been measured. The findings of the 1H NMR shifts at different pH conditions are discussed in relation to the compositions,charges and possible configurations of Co(II) complexes.The stability constants under different pH conditions (pH<3.5) are also determined using the relationship between concentrations of Co(II) complexes and chemical shifts in rapid exchange reactions. |
